Dodge - Dakota :: 2002 - Runs Rough - Won't Restart - Die After Rev
Oct 20, 2011
I have a 02 Dodge Dakota 4.7 liter that is killing me. No codes and no check engine light. From a cold start it starts fine but then runs rough. If I let it run for a few minutes, turn it off and try to restart it, it is very hard to start. Also, if I have it running and rev the engine above 3k rpm and let go of the gas it dies. It will idle without holding the gas pedal down but will die after a rev. Fuel pressure and volume are right in spec. Have good compression, spark and injector pulse on all cylinders. I thought maybe a crank or cam position sensor, but either of those would usually throw some type of code. I thought IAC but it seems to be functioning properly.

My 2002 Dakota with a 3.9 (200,000 miles)has a problem that I cannot seem to cure.When I start the engine it never hesitates....it starts without a problem. No excess cranking...it fires up as it always did.It does run a bit rough as if ONE cylinder is missing every few revolutions. If I let it idle in the driveway for five minutes it will clear up and run fine. But if I take off right away the following will happen.I put it in gear (automatic) and for the first mile or two it runs as though the plug wires (More than one) are wet and arcing. I can barely get above 25mph. it will spit and sputter for that first mile or two.
Then suddenly it will clear up and surge....probably because I have loaded the system with excess fuel......and after it clears up , I have no other problems with it weather I'm on a long trip or a short one. If I stop for more than 15minutes, I have to go thru all this again.I've had vehicles that acted like this after a hard rain because the plug wires were old and arcing...that's why I use that as a description.I also noticed that the other day right at the end of a big downpour it took at least 5 miles to clear up.
Before this rainstorm I had replaced the plugs, wires, rotor and cap, while inside the shop so everything should have been bone dry except for all the humidity from the storm. After starting I checked for any arcing while in the dark shop and even moved a few wires that were touching and no arcing was seen from the cap, wires or coil. I also changed out all those parts 6 months ago when I did a major tune up, but it ran fine untill about two months ago.
When this started two months ago is was just a rare occurrence and my mechanic thought that I had gotten some gas with water in it. He had me run a few bottles of injector cleaner it the next few fill-ups and I've run a few bottles of heet through it also. In the last two weeks it has been doing this every time I start up. When this did start showing up it would show a code of a random misfire and the engine light would come on even though I felt no signs of a misfire myself. The light would stay on for a day or two then go back off. A few days later it was back on.I thought that I fixed the problem because the light stayed off for a month.
So it has been only the last two weeks that it bucks and kicks so bad at a startup, but you would think that an engine misfire would show up and the engine light come on. By the way the light does work. Now, I never get a engine light on, and he found no codes in the history. I have my own scanner, but his can do so much more. I never find any codes also. My mechanic ran some diagnostic's and found an up-stream 0,2 sensor bad so we replaced that.
Yesterday I dropped the tank, pulled the pump and cleaned the tank real good. The only filter is the sock on the pump and that was clean. I refilled with fresh gas and I still have the same problem. So I think that we can eliminate water in the fuel, plugs, wires, rotor, and cap. My next thought is the cam sensor in the distributor.

My '96 Dakota SLT 6-cylinder pickup backfired and blew a hole in my muffler ... I've had it in three different shops on six occasions since and the thing still hiccups, backfires, stalls ... most of the electrical switches and sensors have been replaced ... right before it back fires, it feels like it is going to stall, then "POW" ... sometimes it continues to run fine for a little while after that ... then it happens again ... When it stalls it feels like it is running out of gas ... it is almost impossible to restart right away, but if I wait a few minutes, the starts right up ...

I have a 89 dodge dakota and it starts sometimes and other times it don't start at all. When it does start and runs for a few min it will randomly die and when I try to start it after it dies it wont start back up. Me and my dad just fixed the starter relay yesterday and it started every time after that, now today it wont start. New coil, fuel pump, and fuel filter are new.

Here's what is going on with my 2000 Dakota V6 3.9L V6:
After sitting for at least a couple of hours, the truck will crank but not start. After 3-5 tries, the truck does start but idles roughly at a very low RPM for 10 seconds or so and then stalls. I turn the key one more time and it starts up great and idles and drives normally. This behavior is very consistent. I have only driven it about 5 miles after it started doing this, because on that trip, the engine stalled while I was driving. Occasionally the MIL comes on and gives P0443 as the code. Question is, can the evap purge solenoid cause this behavior if it is going bad? I have inspected the vacuum lines, and they seem ok.
One more note: When this first started, I was pretty sure it was the fuel pump. Replacing that has not fixed the problem, and the fuel pump relay is good.

I have a 1993 Dodge Dakota with a 5.2l MPFI and auto trans that has me and many other mechanics stumped. Recently it stalled on me when I pulled it into the driveway, and ever since it has had this problem.
When I start it up in the morning and it's cold, the problem isn't as bad, but as it warms up it gets worse. It sounds like it's running rough, but its firing on all cylinders. I've verifies this by pulling the plug wires and also the fuel injector wires, and each one will bog the engine down a bit. Also, when I'm cruising or parked, if I hold the throttle at 1000 rpm or less, it loads up and will stall when I let off the throttle. I have to bump the throttle to about 1500 rpm or so when pulling up to a light so that it won't stall on me. When I hold the throttle and it loads up, I can read the o2 sensor with a scanner and it shows 0.8 or 0.9v, so I know it's running rich. If I let off, the sensor reads normal. It's not super rich, but enough that it causes this problem.
Things I've tried so far:
- Replaced plugs, wires, cap, and rotor
- New coil (old one had cracks in the case)
- Checked distributor for play in the shaft, timing chain for looseness, and cam sensor for damage
- Has a new PCM, swapped back to old one and the problem still exists
- Checked fuel pressure with and without regulator, is within specs cold or warmed up, no odd drops in pressure
- Checked all sensors with scanner to verify they read within specs
- Replaced all sensors with known good used AND new and none made any difference (o2 sensor, MAP sensor, TPS, air intake temperature, idle air control, coolant temp sensor)Plugs are brown/tan colored, none are blatantly rich
- Replaced the battery, alternator, and checked all grounds
- Checked the EGR system for correct operation
- Checked for vacuum leaks and broken wires, found none
The truck also has no catalytic converter and only has 1 pre-cat o2 sensor. I also am not getting any codes.

Have a 2002 Dodge Dakota automatic. This winter when temps. dropped into lows 10s and zero degree weather, the Dodge truck would start,but would not come out of park gear. Have replaced interlock solenoid and brake light switch. Still have same problem when Temperature drops into low 10s &below. Otherwise,everything ok. (not using ER brake).

The parking lights come on, the turn signal lights work, the interior lights and high beams work. Could it just be a fuse or two? Dodge Dakota 4WD 2002 ...

I have a 2000 Dakota 5.9 truck that has all of a sudden started to idle rough, loses power over 3000rpm or any kind of reasonable acceleration , with a big sucking sound from the throttle body ( no leaks), seems like it is not getting fuel. Someone mentioned it maybe the "MAP" sensor.

I was asked to look at this Dakota because the Brake warning light and the ABS lights come on.
I get no stored codes with my code reader, and upon test driving it I found that the lights both go off when you shut off the truck, but each time you start up and drive off....those two lights will come on the first time you hit about 30mph and then stay on until you shut off the truck again. Restart and the lights are off until you drive off and hit about 30mph again.
Backing out of the shop, stopping, turning around, down the driveway 50yds and stopping at the road....the lights stay off, even though I just used the brakes three times at least. Get on the road and hit 30mph and they go on.
The two fuses, one in the fuse block by the drivers door and the other (ABS) fuse in the Power distribution box test good.Both brake lights work at the rear as does the high mount brake light. Fluid is at the full mark.
I pulled all four wheels and drums on the back and inspected everything and everything looks good and the E brake cables are intact and working as they should. Brakes were replaced (not by me) and have a little wear, but plenty of material left. No leaks of any lines, calipers, or cylinders. Front rotors are not scored from a sticky caliper, they do have a little minor rusting but because it has been idle for a few months.
I have the same year and drive train in my Dakota. Their truck has about the same stopping power as mine, but I did notice that I did not feel the surging in the ABS as I feel in my truck. I tested this by traveling at about 40mph with the passenger wheels in the gravel and drivers wheels on the pavement and applied the brakes hard. In my truck I felt the surging, but not in theirs. Note that my truck has a tall cap and always carries an extra 800 pounds of gear in the back.Maybe the heavier weight makes my ABS kick in quicker, but I would think weight wouldn't matter.....one wheel is slipping...period.

I have an 2002 Dodge Dakota 8 cyl. 4.7 L engine, 272K. I've gone through 4 fan clutches in the last 2 years and could have gone through more. My mechanic can't figure out why. I've replaced all hoses, radiator, water pump, T-stats, you name it. AC doesn't work either. Probably just a leak. Not sure yet. Why they keep dying on me.

I just replaced fuel pump and tps on my 1989 Dodge Dakota 4 cyl truck. Now it idles rough and the check engine light came on. I have removed battery cable to reset computer but did no good. What could be the problem now? I have since replaced the plug wires and distrib cap and it is flashing 3 5 5 twice now?

So I have a 96 Dodge Dakota SLT 3.9 4WD. Anyway, it idles relatively smoothly at about 700 RPM in drive or neutral, but if I'm in a moving gear and need to stop, the idle is extremely rough. Usually, the RPM's will drop to near 0 within about 20 seconds of coming to a stop. It will typically recover and continue with rough idling and near stalling a few times, but within a minute or two it stalls. A few additional details: it starts right up again after falling, it doesn't make any difference if I start it cold and drive immediately or drive it for an hour before coming to a stop, the same thing happens. Anything that looked suspicious to me has been changed (drive belt, spark plugs & wires, distributor cap & rotor, pcv valve, idle air control valve, and, of course, the air freshener).

I purchased a 2002 Dakota and have had a hard time ridding it. I thought that the heater core was leaking and getting the passenger side floor wet, but it's the overflow for the evaporator under the dash. The drain must be plugged. Will I have to remove the dash to pull the heater unit down far enough to clean it. I don't think I can do much from under the hood...too tight.

This Dakota has the 3.9 with about 240.000 miles. New battery and Alternator within the last 18 months.
The other day after driving about 12 miles the chime "Check Gauges" come on and I noted that the voltage gauge on the dash was buried at Max.Pulled over shut off the truck and popped the hood. No visible problems. Got back in, started the engine and the gauge went back to it's normal position. I had expected to see smoke from the alternator or the battery blown to pieces from the overload. I also noted that there was no excess heat at the alternator or battery.
I picked up my DVM from the shop to carry along and have driven at least 5 trips over 15 miles since. Today the same problem occurred, but by the time I pulled into a close-by parking lot the meter went back to normal. I checked the voltage at the battery and had 13.25 volts with the engine off and 14.40 volts with the engine running. I drove another 40 miles with no problems.
Tomorrow I plan to run a lead from the battery into the cabin, so I can monitor the voltage quicker if the problem reappears.

After I drive my truck and park it for any period of time and then restart the truck it will sputter and backfire rpms do not go over 1500-2000. If I put it in neutral and rev the engine this will work but not always correct the issue. Eventually if I just push through it after 2 or 3 min it will go back to normal. I replaced the spark plugs, wiring and distributor cap. I have also changed the O2 sensors nothing seems to work though.

My 2002 Dodge Dakota Extended Cab pickup is throwing several different 02 sensor codes. The first one was P0132. I reset the CEL and it ran good for about 1800 miles (100,140) on the odometer now. Now I'm getting a P0158 code and CEL went off after a few miles. Now it's back to a P0135 and P0138 code. Are the 02 sensors really bad or is there an underlying problem with the wiring or the computer. The truck runs like new when the CEL is off. The P0132 has never shown up again. The engine is the 3.9 V6 and is 2WD.

I have a 2002 V6 Dodge Dakota that just recently lost pretty much all power. It will not go above 20 mph and has a hard time going up any hills. I was driving on the interstate and initially was having a hard time reaching 65 mph. The truck would roar and then shift and then lose power and shift down a gear. Eventually it lost almost all power and is now barely drive-able. It makes a sound like an ATV at low speeds, kind of a deep humming sound. When I punch the gas in neutral in makes the same sound. I have had problems with it stalling before and am at a complete loss as to the cause.

There is a clicking sound (about once per second) in the front of the engine compartment of my 2002 Dodge Dakota (2WD, quad cab, manual, no alarm, no electric windows, locks, mirrors, etc.) when the vehicle is off (ignition in the off position - with or without key in ignition). It stops if the battery is disconnected, if the key is in the run position, or if the key is in the position that allows one to use power while the vehicle is off. The interior lights and headlights will flash in sync with the clicking sound if they are on as well. The chime that lets you know that the key is in the ingnition with the door open will miss a beat with the click also. The amps running through the circuit (no lights on) jump up from 27 milliamps to 39 milliamps with the click sound. A possibly related issue is that the headlights no longer stay on for the 30 seconds or so that they used to when I turn off and exit the truck after having driven with the lights on. The clicking and light flashing continued even though I removed each fuse and relay in the box under the hood and the one next to the driver door (the lights stopped when their fuse was removed, but the clicking continued).

I have a 2002 Dodge Intrepid that generally runs fine but, on occasion when I turn the the car off and then try to re-start it nothing happens. It has gotten so that I am afraid to drive it, so I am forced to leave the engine running while I run my errands. Other than this one problem the car runs fine.
