Come along with Eric O. as we have a look at this Dodge Dakota with the 4.7L that has an intermittent condition of running poorly and setting a P0300 and a P0303. Freeze Frame Data shows us that the problem occurs during a hot soak and Fuel Trims on bank one drop to -25% short and long term. As with many intermittent problems it was hard to duplicate but we do quickly discover that the bank one is running a tad on the rich side. Could this be causing our problem? Let's see what we find out in the end. -Enjoy!

This video is very intriguing ๐ค definitely looks like that number 7 when it's failing its just dumping all the fuel it can and which makes sense would be causing the miss fire on the other 3 good cylinders Eric O @SouthMaimAutoRepairLLC
Thanks for this video. I'm having a similar issue and I'm buying that otc box today to try mine out
Jasper! I have a jasper 4.7 engine and tranny to put in a 2001 Dakota !
This is happening with my 2004 Dakota. Mine is a 6 cylinder. I don't understand most of what you're saying? It's starting to act up more frequently. It seemed to subside when I only kept it under a quarter tank, but that may have been a two-week coincidence because it's back at it. When I accelerate it acts like I'm running out of gas,usually after it's been running for a few minutes, and smells rich. It's a struggle to get up to 30 mph some days. I imagine people driving around me think I'm driving a stick but don't know how lol. You're explaining exactly what mine does with the codes and flashing light exedra. Can someone explain what's happening in lamens terms? The short story was an injector?
Boring ….. YES …..bring on Mrs O …..that will make things more exciting
You two make me blush!๐Youre a very lucky man sir! Count your blessings!
P0300 Random/Multiple cylinder misfire detected.possible causes
Faulty or worn spark plugs , wires or coils
Distributor failure
Faulty fuel injector
Vacuum leak
Low fuel pressure
Camshaft sensor defective
Crankshaft sensor defective
Engine timing off
Leaking head gasket
Low engine compression
Poor quality fuel
P0303 should not be ignored, and can be a threat to the drivability the Dodge Dakota. The nice thing about P0303 is that it's a cylinder specific trouble code, which makes diagnosing the problems simpler than P0300, which means that the cylinders are randomly misfiring. P0303 is a cylinder specific misfire code, which means that Cylinder 3 is misfiring and causing the code. An important thing to understand when finding the location of cylinder 3 is that itโs going to be the 3โrd cylinder in the firing order of the vehicle, and not the 3โrd cylinder that you might see when looking at the engine.
Fixing P0303 should be considered a high priority. Unlike a lot of the OBDII codes, this code has to do directly with engine combustion. Driving with a misfire can damage the vehicleโs catalytic converter. The engine is also not firing all of the fuel, so raw fuel is also passing through cylinder 3 into the exhaust. Mileage may suffer as well when your Dakota has P0303.The P0303 trouble code will trigger the Dakotaโs service engine soon light. The vehicle itself may begin to run rough. It depends on how serious the misfire is, and how many cylinders the engine has. The vehicle may produce excess vibration, especially at lower RPM. Fuel mileage will suffer (often not drastically). You may smell raw gas coming from the tailpipe. The vehicle may backfire. There are quite a few things that can cause the P0303 trouble code to trigger the Dodge Dakota . Here are the most common problems that will throw the code. They are presented somewhat in order from most to least likely to be causing the code:
Bad Spark Plugsโ Spark plugs are one of the most common causes of P0303. Take a look at the electrodes and see if they are in good shape. Most vehicles now come with iridium plugs that need changed very infrequently. That being said, the plugs are a great place to start. Hereโs a great video on how to see if a spark plug is bad.
Spark Plug Wiresโ On most modern engines, the plug wires are not nearly as long as they once were, but they can still go bad. Hereโs how to tell if your plug wires are bad (video).
Coil Packsโ Coil packs rarely go bad, but when they do, they can certainly cause P0303 in your Dodge Dakota. Replacing a set can be very expensive. Hereโs how to test them.
Bad Fuel Injectorโ If you have a fuel injector that has gone bad, it wonโt be able to properly atomize the fuel and youโll get the P0303. Hereโs a good video on how to diagnose an injector, it can be a little tricky. This is definitely not the place to start.
Vacuum leakโ If your Dakota has a vacuum leak, it can be very difficult for it to get the right air/fuel mixture. This will cause the cylinders to misfire and itโll throw the P0303 if the leak is around that specific cylinder on the intake manifold. Itโs easy (and kind of fun) to chase one down. Popular Mechanics: How to find a vacuum leak.
Cam or Crank Sensorsโ This one is very unlikely, but it does happen. If the ECU is not getting the right signal from these sensors, the vehicles timing is not going to sync up and itโll misfire.
Low Compressionโ If you have a leaking head gasket, bent valve, cracked head, etc.. that would cause compression to not be as high as it should, youโre going to get P0303. You should also feel the vehicle is down on power as well. P0303 is cause for concern and left unfixed can leave you stranded or make the vehicle virtually undrivable.
Hmm I have been dealing with p0300, p0301, p0303 and p0305 for over 3 months now. I'll have to check out that upstream O2 sensor sometime soon. Just afraid of destroying the threads..
I have an 07 dakota and the rpm ans speedometer spike up when I'm braking..any idea what that could be?
You just got another subscriber, ME๐๐
dont know if you know ebay has adapters to adapt that plug on your tester to any other injector. like i have a 1994 ram 1500 i installed a 2002 5.9 magnum motor as you know the plug on the injectors changed from 1994 to 2002 i ordered a whole set of adapters
EV1 to EV6 may have that backwards but have been on the truck for 5 years still runs great. so you can order one at a time or a set. that is what i did for my injector tool that i have makes it so easy
After watching this video I wanted to see if you might be able to assist me with my own truck. I have a 98 Dakota with the 3.9 liter V6 and I'm having a lot of the same problems as the truck and video the only difference is I'm getting codes P 0300, 0301, 0351, and a 0132. I do already know that those three codes are misfires and the last code is my O2 sensor bank 1 sensor 1 running rich. I can only assume that the sensor is the problem that I have having because I cannot get it out which tells me it is probably been in there for 22 years. If you have any other advice it would be greatly appreciated.
Great Mr owe this is fantastic
Had a 99 power wagon per paint bank 1 had one set of 4 injectors and bank 2 had a different set of injectors took 3 days to notice it the two different types of injectors that fired at different portions of fuel to the engine the higher on the right the lessor on the left after 2 weeks we finally worked it out with a matched set of 8
Got the woodstove going.
I had one of these bastard in my shop..kept spitting rocker arms off when started cold.
Hi folks, both alive and dead like me. A bad coil code with 3 and or 7 cly is a misdiagnosis, the cause is likely to be the emmisions system. The can or fuel vapor canister can have split or collapsed vac hoses. Try to block them and it can create a bucking problem when floor and a shitty iratic idle. Shops and scanners used may not have the software to do a vacuum pressure test. So make sure the gastank vapor system supply lines are good and routed to the correct ports.
Just purchasing this exact year and model..thanks for posting
title Quote " Dodge Dakota: intermittent skipping, bucking, poor running" I had the same thing happen to me and it turned out to be the two wire pigtail connecting to the coilpack on my number 1 cylinder. I changed the PCM and had dodge dealer charge me 300 buck to change the #1  pigtail on the both of those injectors. bought a new coil pack, finely figured it out to be the #1 coilpack two wire pig tail.
I like your name, my name is Eric to. No codes, no check engine light.
Just changed IAC/TPS still runs at about 500 to 600 rpms i want to be around 900 to 1000 rpm at idle
It's a 2001 dodge dakota 4.7 any other possibilities. please any help.
my ecm burnt-out brake lights and turn signal/flasher when the pigtail trailer connector shorted out – was wondering if the brake light switch on the brake pedal-bar switch can be direct wired ?
My 06 dakota with the 3.7 miss fire no codes
Did you record that accident, sending a tool up in smoke?
OK Iโve watched so many videos on misfires Iโve seen a lot of yours and ends up being something so easy my situation is I have a P0300 and p0303 to Start so I thought Iโm going to put new coilโs new spark plugs new injectors and I was hoping that he would take care of the whole situation well Iโve gone to crank Sensorsand Iโve gone to camp sensors and Iโm having the same situation so the next thing that I thought it can be my lifters but the other day my battery died I got it charged and I turn the truck on I drove it for a half a day half a day and the truck ran great no misfires no funny feeling nothing and then after a while we came back so what do you think thatโs telling me that itโs mechanical or still something electrical I really need help
Damn the money light… Check out that massive body rust!
I don't know why everyone is knocking on the Dodge Dakotas…. I think they're great. I find them all the time in fairly new condition at the junk yard! Best parts money can buy.
Another Great Video! I've seen Part 2. I agree, should change the 4 injectors.
My 2005 Dakota has 191K miles and runs great! No engine problems, only had to replace the EGR at 50K.
I hoave 06 Dodge Dakota it has a P0 300 too but it only misfires when I first Crank It Up what could it be please help
Eric, go the junk yard with a pair of side cutters in you back pocket and harvest a nice selection plugs and make your own adaptors.
But be careful the rubber seal may tear. So if you do take this route proceed with coucion unless you have more injector seals lying around.
I think if you could have swapped the #7 injector with say #3 injector to see if the psi was to drop in #3 and stay in range in #7. Like you could do in bad coil over plug diag.
Damn that's some serious body rust. Same as here in maine
lol I used an led bulb a count the pulses.
Mine happened the day I went for inspection after I waited till the last day of the month for inspection
I had the same problem on a 00 jeep XJ it was my injectors and it blow my 02 sensor
Eric O, would you not only want to double check the same cylinders, but also check the cylinders in the other bank to have a reference to go by , and compare them all ? Just wondering what a known good should be.
Alabama, 40 Hour Week (for a living) has a line(s) very close to what you were looking for: "Hello Detroit auto workers,
Let me thank you for your time
You work a forty hour week for a livin',
Just to send it on down the line
Hello Pittsburgh steel mill workers,
Let me thank you for your time
You work a forty hour week for a livin',
Just to send it on down the line."
Dodge a dodge. Problem solved.
Next time you are at the junkyard grab some different pigtails and make your own adapters.
many thanks, Eric, All the best for the new year to you and your family including the dogs, god bless.
Hmmmmm. Interesting.
I have the matco unit. Comes with 4mm banana style connections to the box. Combine that with the AES wave terminal kit and thereโs nothing you can adapt to. Never had a problem with wires coming off.
When you yelled at the camera to focus I was waiting for the "you fack" after it. I guess I been watching AVE too much ๐
Great video. So fun to watch. What's your brother's channel?
Soak it with water it may fail when wet
99% of tech would say "I can't duplicate the issue" and give it back to the customer. Not Eric O. !
I would never have thought to use and injector pulser to test injector VOLUME, but by starting with a ๐๐ข๐ฑ๐๐ ๐ฉ๐ซ๐๐ฌ๐ฌ๐ฎ๐ซ๐ ๐๐ง๐ ๐ฏ๐จ๐ฅ๐ฎ๐ฆ๐ (๐คโ๐๐ก ๐๐ ๐๐ ๐กโ๐ ๐๐๐๐๐ ) and NO pump, that is exactly what you are doing by looking at pressure drop !!
Hey Eric, I'm not familiar with the scan tool you are using, but, I know most tools will toggle the fuel pump relay, as well as the ASD relay, which would save you the whole key toggling thing.. Just a thought..
