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 🤔 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

    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?

    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 it’s going to be the 3’rd cylinder in the firing order of the vehicle, and not the 3’rd 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 vehicle’s 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 Dakota’s 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 Plugs– 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. Here’s a great video on how to see if a spark plug is bad.
    Spark Plug Wires– On most modern engines, the plug wires are not nearly as long as they once were, but they can still go bad. Here’s how to tell if your plug wires are bad (video).
    Coil Packs– 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. Here’s how to test them.
    Bad Fuel Injector– If you have a fuel injector that has gone bad, it won’t be able to properly atomize the fuel and you’ll get the P0303. Here’s a good video on how to diagnose an injector, it can be a little tricky. This is definitely not the place to start.
    Vacuum leak– 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 it’ll throw the P0303 if the leak is around that specific cylinder on the intake manifold. It’s easy (and kind of fun) to chase one down. Popular Mechanics: How to find a vacuum leak.
    Cam or Crank Sensors– 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 it’ll misfire.
    Low Compression– If you have a leaking head gasket, bent valve, cracked head, etc.. that would cause compression to not be as high as it should, you’re 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..

  9. Avataaar/Circle Created with python_avatars Jesus Cotto says:

    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, ME😁😁

  11. Avataaar/Circle Created with python_avatars Dependable Auto Truck says:

    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

  12. Avataaar/Circle Created with python_avatars Kenneth Lee says:

    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

  14. Avataaar/Circle Created with python_avatars Shane Harrison says:

    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

    I had one of these bastard in my shop..kept spitting rocker arms off when started cold.

  17. Avataaar/Circle Created with python_avatars Marshall Fredrick Neblina says:

    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

  19. Avataaar/Circle Created with python_avatars Michael Kabriel says:

    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 &#2 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.

  20. Avataaar/Circle Created with python_avatars E Von says:

    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.

  21. Avataaar/Circle Created with python_avatars Tim Tremblay says:

    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 ?

    Did you record that accident, sending a tool up in smoke?

  24. Avataaar/Circle Created with python_avatars Marcelino Duran says:

    OK I’ve watched so many videos on misfires I’ve 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 I’m going to put new coil’s new spark plugs new injectors and I was hoping that he would take care of the whole situation well I’ve gone to crank Sensorsand I’ve gone to camp sensors and I’m 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 that’s telling me that it’s mechanical or still something electrical I really need help

    Damn the money light… Check out that massive body rust!

  26. Avataaar/Circle Created with python_avatars Cheapirishbastard says:

    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.

  27. Avataaar/Circle Created with python_avatars Mike Chiodetti says:

    Another Great Video! I've seen Part 2. I agree, should change the 4 injectors.

  29. Avataaar/Circle Created with python_avatars Edward Valdes says:

    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

  30. Avataaar/Circle Created with python_avatars Harry Sanders says:

    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.

  31. Avataaar/Circle Created with python_avatars Chris Bayne says:

    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.

  32. Avataaar/Circle Created with python_avatars Chris Bayne says:

    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.

  33. Avataaar/Circle Created with python_avatars Austin316 says:

    Damn that's some serious body rust. Same as here in maine

  37. Avataaar/Circle Created with python_avatars Tracy Sellman says:

    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.

    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 𝐟𝐢𝐱𝐞𝐝 𝐩𝐫𝐞𝐬𝐬𝐮𝐫𝐞 𝐚𝐧𝐝 𝐯𝐨𝐥𝐮𝐦𝐞 (𝑤ℎ𝑎𝑡 𝑖𝑠 𝑖𝑛 𝑡ℎ𝑒 𝑙𝑖𝑛𝑒𝑠) and NO pump, that is exactly what you are doing by looking at pressure drop !!

  48. Avataaar/Circle Created with python_avatars Adam Trombino says:

    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..
