It's now time to get that #7 injector up and out of the engine and see what kind of fuel corrections it makes in the long term with the new fuel injector in place. Will it be the fix? Was it the correct approach? Time will tell... -Enjoy!

    Nice work on the diag the fuel Trims look pretty good now I do agree could have used the Cylinder 5 injector also but looks a ton better since the 7th injector was changed out much better then it was Eric O @SouthMainAutoRepairLLC

    I have the same issue, I will look at the fuel injectors, thanks for putting up your work, much appreciated from San Diego

    Ur videos have helped me narrow my problem to injectors thank you

  5. Avataaar/Circle Created with python_avatars L.A. Commander says:

    I replaced the intake manifold on my Explorer 4.6L V8 a couple years ago and while it wasn't a difficult job, the only hard part was getting those 8 fuel injectors out. I can't tell you how long I struggled with those guys. I think that alone may have been half the time of the whole job lol.

  7. Avataaar/Circle Created with python_avatars EDDIE LEAL says:

    Read an article on Repair Pal website stating that surging or bucking during acceleration can be attributed to a distributor that is moved or mis-indexed. This is a result of the cam and crank position sensors being out of synchronization. Wear of the oil pump drive gear may also cause similar symptoms because it allows excessive free play in the distributor drive. The distributor drive gear and bushing should be replaced if the rotor tip moves back-and-forth more than 3/16th of an inch when checking drive gear free play.

    where did you find the T handle would love to have one thanks

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

    @SouthMainAuto I have a 98 Dakota 3.9 V6 with a similar problem. Truck runs fine until I shut it down, then restarts super easy. After restarting and driving around a little bit it starts bucking, and stalls. My fuel economy is so far down that I can't see it, and the last OBD II scan showed me a P0132, P0300, P0301, and P0351. Ignition coil is brand new, so I'm not sure why the 0351 is still showing. Please tell me anything you can think of that may help me. Thanks.

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

    Why would you replace injectors that arent broken or damaged that counter productive isnt it .

  14. Avataaar/Circle Created with python_avatars Chris H says:

    I understand it was going to die in a year or so.May be work on nearer cars that people would pay a little more for. If I find one bad Injector,one bad spark plug or coil or wire change them as a set.

  15. Avataaar/Circle Created with python_avatars ZG 1K says:

    Thank you man. I've been chasing a P0300 with similar symptoms for awhile now. I suspected an injector issue, but I never expected a bad injector to cause an entire bank to misfire. When I first got the truck, it had a p0305 and p0300 as well as a code for fuel level among other things. After replacing the fuel pump and plugs (both needed) and fixing the vacuum leaks, head gasket and replacing a leaking radiator this p0300 was all that was left haunting me. Truck would occasionally run beautifully getting 19 mpg on the freeway, but then it would start missing and drop down to 11 or so. I tested the coils more times and ways than I care to admit because intermittent usually means electronics. I used a stethoscope and screwdriver to listen to the injectors, and they were all ticking every time I checked (truck didn't idle that rough honestly). Sure enough, cylinder 5 injector was swollen down where you can't see it from the top. My guess is, some of the coolant from the leaking head gasket had caused the injector failure. Have a full set of injectors coming for mine though.

    On a side note, anyone interested in buying an 02 Ram 1500 4.7 SLT? 😛

    I have a 1995 Dakota 3.9 Magnum engine that is brand new. I installed it last fall it has about 10.000 miles now. When the engine was put in every sensor and injectors plugs wires belts everything under the hood is new. I was having a serious problem after the engine warmed up sputtering and shaking while under power. No check engine light was on. To make long story short the crank position sensor was bad even though it was new. I changed it on advise of a friend and now my truck runs as it should. I hope this helps Dodge Dakota people.

    Eric, how it goes! I am hoping you can help me as i am in a real jam…my 98" Durango 5.9 just today blew the 50 amp ignition / starter fuse in the PDC. Didn't know until returning home …while driving (abs light, airbag light illuminated, and the windows are stuck down, and the heater/ac controls do not work ) found it replaced it and it blew again! I have had weird instances only when the engine was warm after driving and then re-starting (i.e stopping at the store ) when turning the key to start it would crank , hesitate, (like lose power for a split second) and then start…and or it would start super quick like with no crank, just vroom and start!

    research is showing me a short somewhere, but could the starter and or the Solenoid just be bad? Any insight at all would be greatly appreciated, the truck is stuck at the bottom of driveway with windows down (luckily no rain for a day or so hopefully) but I need to figure this out and quick!

    I did do the heater core last year and had the dash down but not out all the way (steering column was dropped) out! Is it possible I damaged a wire up there on the column harness? The truck is about 70% restored as I have put 14 G into it the last 5 years, so it is in pretty good shape overall! I have a used new motor in it w 105K from a rusted out dakota, but the engine didn't have much if any rust! This was 4 years ago as well and have not had any issues other than that random starting thing! The truck has 325K so assuming the starter is the original could it going bad be the issue?!

    Thanks in advance brother!!

    Great job again like always

  19. Avataaar/Circle Created with python_avatars Shane Heiden says:

    I recently pulled my 4.7l because the rear tabs on the transmission case were cracked. Thinking it was caused by worn engine mounts, I lifted the engine about 6” to replace the mounts and rusty oil pan. When pulling the wiring harness, a majority of the bank 1 injectors leaked at the rail. So I pulled the fuel rail to replace the o-rings. All of my bank 2 injectors had cracks in the plastic body. The engine ran fine. Since I noticed the fan clutch was leaking and one of the coils was corroded inside I stopped at a pull your parts to get a coil and clutch. I planned to pocket some injectors while I was at it. I pulled the injectors from three 4.7l engines and they were all cracked. I took the “best” four to keep as spares, but they turned out to be a different part number than my originals anyway. The plastic at the bottom was red as well instead of the white on mine. Anyway, I’m still running the originals with no issue. You got luckier than I on the rail bolts. I snapped the passenger rear one off and it’s a M10 instead of an M6 now. This all was a result of looking into why my referees lights weren’t working and checking the switch on the nv3500 trans. Of course I did the hanger bearing and u-joints while I was at it.

    I truly enjoyed watching your videos on any dodge dakota truck. Please keep it up. Thank you.

  21. Avataaar/Circle Created with python_avatars SingleCab Steve says:

    It's so much easier to just pull the intake plenum and pull the CPs. Move the PVC and the plugs off the TB and move the two coolant lines and you have a ton of room. It takes 10 minutes. Saves you soooo much frustration.

    that was one cool prybar you was using

  24. Avataaar/Circle Created with python_avatars forty two says:

    Wow! It looks like somebody dipped that truck in the ocean. A lot of rust. Is every vehicle out there like that? Horrible!

  25. Avataaar/Circle Created with python_avatars GNX157 says:

    Eric, wanted to relate a rich running case I saw on a GDI engine where the high pressure mechanical pump was driven off the camshaft. So bad the engine fuel management was maxed out trying to correct a rich condition and so bad you could smell raw fuel at the oil cap and also oil level overfull. Well long story short, the hi pressure fuel pump backside shaft was leaking raw fuel right into the engine. Somehow these fuel pumps should have a design where that leaking fuel is detected and also routed back internally to the fuel tank instead of into the engine.

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

    Great instruction Video on how injectors affect fuel trim!

  27. Avataaar/Circle Created with python_avatars Hola! Ed Axeman says:

    I'd bet at some time during cold weather, water in the fuel ended up in that injector, froze, swelled and cracked it. I've seen throttle body injectors blow out big time that way. More stuff they never see in the south! Also, it's possible that cylinder is a little washed out and not sealing properly. I guess I would have made sure the oil was good too, especially if it sees a lot of short trips in the winter.

  28. Avataaar/Circle Created with python_avatars John Ferguson says:

    A little swipe of silicone grease on the fuel injector O-rings will make it much easier to install and later remove them.

  29. Avataaar/Circle Created with python_avatars zac hill says:

    know any good speaker replacement videos and on my 1998 Dakota the eltEric locks dont work im not to worried as it is a 5 speed and most folks nowadays dont know how to operate them

  30. Avataaar/Circle Created with python_avatars A Day says:

    I see you using that classic reach around trying to get that #7 injector into the hole. Have you ever just tried talking dirty to the vehicle to see if that will work:)

  31. Avataaar/Circle Created with python_avatars Brian Skinner says:

    Question is your state have restrictions on years for owning vehicles. I thought you said it had 1 year left before it goes into the recycle bin

  32. Avataaar/Circle Created with python_avatars Opie Leslie - WPMABB says:

    That truck has 10 more years easy, put some wax on that thing, an LED upgrade and stuff.

  33. Avataaar/Circle Created with python_avatars Ozzstar's Cars says:

    Yeah I always lube my injector before sliding it back in the hole, good advice.

  34. Avataaar/Circle Created with python_avatars Mike Miller says:

    All 6 injectors on my Jeep 4.0 are cracked. One of these days I will replace them

  42. Avataaar/Circle Created with python_avatars TermitesRGood1 says:

    1 year before the SCRAP YARD??? WTF looks goods to me just needs cleaning,some people wish they had that truck in this condition…. just toss a new create motor in it $12k or 50k replacement on the truck.

  43. Avataaar/Circle Created with python_avatars Rivs says:

    Great job on the diag for that dakota. Enjoy watching your videos and picking up tips and tricks. I've done everything on my vehicles for the past 10+ years aside from tires and alignments, so the extra knowledge comes in handy.

    Keep the videos coming
