#17 of 37 Help for the '97 Dakota Truck guy!
Mar 18, 2009 (7:31 pm)
I posted to Maddux 8848 instead of listing my problem separately. I have the same problem with my 1997 Dodge Dakota Truck. I've replaced the crank sensor, fuel pump, cam position sensor twice, plug wires, plugs, distributor,
coolant temperature sensor etc. There is a 1999 van having the same symptoms and the dealership has not figured it out. When it is cold, it runs well for 10-12 minutes and then bucks and misfires so much it feels like it is ruining the truck. When it is warm, it runs like a top. I need help too Dusty! I have about 155,000 miles on my standard transmission Dakota. Chrysler wants to start throwing wiring harnesses at the van and if it was that would not the vehicle have ongoing problems in any weather? I did not mention my mechanic also put a new computer on the truck to test with all the same results! I also have the 3.9 Magnum engine. Any help is greatly appreciated. It is nice to have all the new parts, but if it still runs lousy I'm just going broke and keeping my mechanic busy!

the truck has 140,000 miles and does not smoke or use any oil.engine has absolutely no blowback when you pull off oil cap as it runs.my biggest problem the idle.It doesn't run real bad at iddle just idles way to high and hits trans to hard when put in gear.if it wasn,t for that you would have no problems driving truck other than idle up and down in high gear(overdrive).one other thing i forgot you can hold throtle at 2000 rpm and it will go from 1500 to 2000 on its own while holding gas pedal in same spot.my mechanic says it is either the IAC or the valve body needs good cleaning.he says he just fixed one doing the same thing. what do you think dusty will i be wasting my money doing these two things.thanks alot

All I have to say to "factman1" is ...DITTO!! I'm having exactly the same problem w/my 1997 Dodge Dakota....I've replace the crank sensor, cam position sensor, plugs, wires, new timing chain...etc............... Mine got so bad, (exactly like yours, when cold it runs great for the 10+ minutes, then bucks and misfires, when warm runs GREAT....) that with one big backfire, I blew out the "dougnut"...big deal, so I'm putting up with sounding like I have a "hemi", I'm not fixing it until someone can give me a solution to the problem. Summer is coming and it will operate fine, but then comes winter again. I had a friend suggest replacing the fuel pump sensor and such, but...crap I've already spent how much on stupid sensors that the "intelligent computer diagnostic crap" told me was wrong!

Well, just going by your description I'm not sure. A abnormally high idle can be caused by the Idle Air Control (IAC) Motor. A sticking IAC pintle could cause the same thing. At 140,000 miles a gummy throttlebody is a likely candidate for this problem, especially if you've used subpar fuels lacking a good detergent package.
I'd also consider a sticking or weak PCV valve or a vacuum leak. They can cause idle problems, too. Around here '99s of any make or model start to suffer from brittle and split rubber hoses.
Other possibilities include a defective Coolant Temperature Sensor (sending an intermittent signal to the PCM), or bad connections to the PCM or IAC motor, or a bad MAP sensor.

I would check the distributor next. I was having the same problem in my 1992 dodge dakota and it led me to blown head gasket and i looked at the distributor. beneath the hall effect pickup there is a piece of metal that spins. if that comes loose or gets damaged it can act like your motor is out of time. Which causes it to loose power and stall out at times.
watch your wiring harness when in there!

thanks alot dustyk i hg\ave fixed idleing problem by replacing IAC sensor.truck now almost idles perfect.but since getting the truck idleing good i am noticing another problem with truck.the truck surges alot when you reach speeds over 60 mph.Its almost like trans is gearing up and down from overdrive to drive.my mechanic ran scan and found crank sensor problem and replaced it and it help the sluggish nature of truck but did not fix surging.I don't know what else to do i have replaced everything that a shadetree like myself can think of.all i know is i can't keep spending money in this truck, i love it but not that much.I would any input on this problem you may have it would be greatly appreciated.thanks
#23 of 37 Help with my 99 Dakota
Jun 17, 2009 (9:27 pm)
Hey there! Before yesterday I have never had a problem with my truck. I have a 99 Dodge Dakota 2wd 5speed with the 3.9 V6 Magnum engine. Yesterday it Drove great. Until i let it sit for an hour or so then tried to go to my bank. I took off shifted into 2nd, it seemed to just lag. i didn't move my foot from the accelerator pedal, but it slowed down and the tach gauge would drop slightly. Let my foot off the gas and slammed it back down, it took off. Did the all the way up until the end of 4th gear. But If i hammer on it, and shift it at a higher RPM throughout the gears it seemed to not do it. I just don't know where to start!! Any ideas??
#24 of 37 Hard restarting
Jun 30, 2009 (9:07 am)
I have a 93 Dakota 3.9 with 104K miles on it . It will restart in the winter, but when it's hot, it won't restart until it has cooled down. Then it runs fine. This last time, I got a "check engine" light and pulled the codes. It had a # 22 code, (ECT sensor voltage too high). Could a bad sensor cause this non starting problem? Thanks in advance for any help.

i had the same problem for a year. it is definately the CPK, or crankshaft posioning sensor. they work by sensing a magnet on the crankshaft and sending the signal to the computer telling it when to fire.
it's sually by the bell-housing or on it. you can try to clean it, because grease build-up can block the magnetic signal. this might save you money and hassle.
the part has a square end on it, wipe that off good and then try it.

Thanks Herb for the info. I did change my coolant temperature sensor and that seems to have fixed the problem. Although, as all owners know, your vehicle loves to play little tricks on you and it may show up again. If it does, I will change the crankshaft positioning sensor as you suggested. Thanks again for the help.
