Replying to: fbjr55 (Oct 08, 2009 2:09 pm) Dont you wish that mechanics only get paid IF THEY FIX IT?   BTW, if you have had the very same sensors replaced several times... I hope you realize that you do not have to pay for any more than the 1st one. All Dealer parts are waranteed and if they have to be replaced again, the original part must have been bad so it is 'covered'.   Personally, I cleaned the IAC . (Idle Air Controller) once a year when I had the 4.7L semi-hemi engine. This always improved idle smoothness.   Dont forget that your 4.7L has COP (Coil On Plug) ignition. The coils are swappable if you need to isolate a bad one.

Replying to: dchap110 (Oct 09, 2009 4:24 am) Bummer. Hope you haven't hurt your engine.   Not aware of any free on-line manuals. The manuals, either those from the manufacturer or from a third party are copyrighted. Posting them would probably be a violation of copyright law. There are some on-line sites where you can subscribe to manuals for an annual fee, I think.

Replying to: dchap110 (Oct 09, 2009 4:57 am) Before you replace the oil pump, have you tried a good cleaning?   My daughters 1st car tended to 'rattle' when the engine got hot. This was because the hydrolic-lifters were so cruddy that they would not hold pressure.   I ran some "STP oil treatment" in it.... that INSTANTLY fixed the oil-pressure. (because it is a viscosity-improver.)   The next time I changed the oil, I expected the rattling to come back.... to my amazement, the "STP oil treatment" other feature (detergents) had cleaned out the lifters and that car never-again had that problem.   Also, you may wish to run a slightly-thicker oil... this is a MUCH less expensive way to resolve such a problem.

Replying to: bpeebles (Oct 08, 2009 5:16 pm) Thanks, however I am being told that there is a bad connection or computer. Currently I have trouble codes 352 351 357 and 1391. 1391 is loss of signal from crank or cam shaft sensor. Both of these have been replaced. In addition the truck has been blowing the fuse for the ASD relay. My funds have allready been exhausted in trying to fix this. My thought is if it is a wiring issue, then the codes and the blowing fuses should help isolate which wires to check first. Thanks in advance for any guidance you can give me.   Also something I found out that I was unaware of. If you turn the ignition on and off three times, your trouble codes will show on your odometer. Cool. Just wonder why I have not seen it in any of the manuals. Replies to this message: srs_49 (Oct 23, 2009 2:27 am) header1974 (Oct 23, 2009 5:01 am) bpeebles (Oct 23, 2009 2:38 pm)

Replying to: fbjr55 (Oct 22, 2009 5:14 pm) Cool. Just wonder why I have not seen it in any of the manuals   Because they want you to bring the truck into the shop for a service visit and be able to bill you for it.

Replying to: fbjr55 (Oct 22, 2009 5:14 pm) Not sure with that many codes. What is going on with acutal running of the truck? are there any mechanical issues you can notice? If not then I might think about disconnecting negative cable to battery and the reconnect 15 minutes later. It might reset itself which happen with my truck when I replaced the TPS. Did you try this when you replaced the carak and camshaft sensor? I know that when I did this is reset the computer and no longer got the code this was after fixing the problem. let me know if this works Header1974

Replying to: fbjr55 (Oct 22, 2009 5:14 pm) Just wonder why I have not seen it in any of the manuals. The FACTORY shop manual clearly explains this (and many other) troubleshooting capabilities of your Dakota.   *)The FACTORY shop manual has step-by-step instructions how to troubleshoot/isolate most problems. *)The FACTORY shop manual lists, diagrams and locates EVERY electricial connector in your Dakota. *)The FACTORY shop manual has paragraphs describing EVERY component and its function. (Automatic-xmission chapter is 100s of pages)   I suspect you are not looking in a FACTORY shop manual. All the other ones (Chilton, Hanes...etc) have no connection to the factory and are very careful to NOT infringe on copywright of the FACTORY shop manual.... thus they necessarrly do not have the same content.
#370 of 378 1995 dakota 3.9 a/t shuts off by biggdlr59 Oct 24, 2009 (2:53 pm)
I have a 1995 dakota 3.9 a/t that shuts down after 5 to 10 minutes. I have to wait 45 minutes to 1 hour before it may or may not start. It may or may not run for 5 to 10 more minutes. Replaced the magnetic pick up in the distributor,and the fuel pump relay. I then took the truck to aamco for a scan and was told it may be a bad wire in the computer or the computer it self. please anyone HELP BEFORE I SET THISTRUCK ON FIRE!!!!
