I have a '99 Dakota 4 cylinder. Starts fine but as it warms up or if you gas it the idle stays high. The more you run it the higher it goes. Have replaced MAP senser, throttle position and air bypass with no effect.( map and high tps voltage only codes shown ) Vacuum problem?

The vehicle exhibits an intermittent high idle. I have replaced the usual IAC stepper motor and checked the tps for proper function, also completely cleaned, inspected and relubed the throttle body and linkage.
According to my Inova 3140, there are no codes and the temperature sensors and tps percentage are reading correctly. Also the battery and charging system are functioning correctly.
I do not have bi directional capability or the ability to monitor any of the pid'sOne other thing is that she also has a slight rough idle, but that could be the 200,000 miles.
I have this whistling noise coming from the front area of my truck (97 dodge dakota) 4X4. The noise sounds like air at high pitch (just my opinion and friends), happens around 30 to 40 mph when you hear the whistling noise. I've taped all holes and gaps that might be causing the sound but no avail. I've had a friend look at it, that's a fire truck mechanic and no luck and he said it didn't sound like wheel bearing problem.
View 1 RepliesI have a 2007 dodge Dakota with 112K miles. At 105K I had the front brake rotors and pads replaced. The rear brakes were fine. There was a problem with one of the rotors and I returned a week or two later and one, which was warped, was replaced. Ever since that second visit I have had an intermittent vibration from the vehicle. When I brake the whole truck vibrates. And by vibrating, I mean some pretty heavy shaking. It is not the steering wheel vibrating. I took this back to the mechanic where they were unable to find any issues with the brakes. Also, we could not (of course) re-create the issue while it was in the shop. I have not been able to find the pattern. It happens when I am braking at high speeds, but not every time. It also happens at lower speed, but again, not every time.

View 4 RepliesWe have a 1996 Dodge Dakota SLT that we purchased used. It starts and runs beautifully when the engine is cold; however, if you turn the vehicle off it is difficult to get it restarted and to keep it idling without keeping your foot on the accelerator. The funky thing is that after your "fight" with it a few minutes (i.e., foot constantly on the accelerator), the truck will then start to run correctly and idle correctly until the next time you turn off the engine. We have noticed that on each occasion when we have had this problem, the engine smells EXTREMELY flooded. We've been told its a temperature sensor, any other number of sensors, and now the IAC. If starting by process of elimination with least expensive fix first, what the heck do we replace first?
View 4 RepliesHere'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.
This is an ongoing problem that has lasted for several weeks now -- I’m completely flummoxed and at a loss. It goes something like this:
My truck (2000 Dodge Dakota, 2.5L, 5-speed) has developed -- for lack of a better term -- a high-pitched whining squeal, which only occurs after I put it in gear and actually start moving (if I leave it idling in neutral, when starting it after letting it sit overnight, the sound usually does not appear at all). After about three or four minutes of driving time, the sound will show up, but there’s an odd twist: the sound is most apparent, and really loud, when the truck is at idle, such as when at a stop sign or traffic signal; when I put it in gear and take off, the noise will drop in pitch and, depending on how hard I’m pressing on the accelerator, it sometimes disappears altogether.
When I take off, every time I shift gears the sound returns -- only for as long as I step on the clutch and back off the gas, and when I step on the accelerator again the noise falls in pitch and vanishes. It does this off-and-on thing through all the gears, and after reaching the desired road speed (and I’ve reduced pressure on the gas pedal) the sound returns and is constant. Also, if I shut the truck off and wait just a few minutes, and then fire it back up, the sound will be gone, but will return after a short while, exactly as related above. It’s worth noting that, during all this irritating misadventure, the engine has run exactly as it always has -- there’s been no discernible impact on performance.
Now, some considerations. The noise is louder and more strident when the ambient temperature is lower, such as in the morning. Later in the day, when the temperature rises, the sound becomes erratic and somewhat unpredictable, and is much lower in volume, and it will even stop abruptly and then reappear later.
Many people have suggested that it could be the belt or a pulley, maybe. I replaced both tensioners and even installed a new, shorter belt to bypass the A/C compressor (to eliminate it as the possible culprit), but the noise remains. I was skeptical of all that because -- and please correct me if I’m wrong -- a shot pulley making such a horrible racket should get louder as engine speed increases, not drop in pitch and disappear. In fact, the noise seems to have no relation to engine RPM; if anything, it seems tied somehow to intake manifold pressure (the sound vanishes when the truck is accelerating, which is when intake manifold pressure goes down, or so is my understanding), or throttle position, or something else entirely. The vacuum system? The noise seems mechanical to me, not like escaping air (or, well, vacuum) . . . but what do I know?
Cold start. engine starts but wont idle, just dies. rpms drop. Restart same. Must neutral drop to get going keep rpms up until engines shifts then things are fine until next cold start. Cleaned throttle, changed air filter, dry gas, injector cleaner, no warning signal, scans clean. 180k miles.
View 6 RepliesI 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.
View 2 RepliesI 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?
View 10 RepliesI drive a 2000 Dodge Dakota Sport w/ 4.7L V8 engine. I have been dealing with an overheating problem for about 6 months now and have nearly exhausted all hope of correcting the issue. It has been in the shop on 4 separate occasions and seen 2 different mechanics. The radiator has been replaced, the thermostat and thermostat housing have been replaced, the radiator fan works properly, hoses have been replaced and no subsequent leak has been found by either mechanic, they haven't mentioned the possibility of a blown Head Gasket (nor has the typical "milky residue," shown up in my oil cap). Each time I got it back from the shop the problem was fixed for about two weeks, then returned and slowly got worse.
It overheats in idle (with the fan running), on the highway at high speeds, and while driving slow. Sometimes it only gets about 3/4th to the red (usually when its cool at night) and sometimes it will hover just below the red; while I'm doing everything I can to keep it from hitting red (defrost on, revving engine). Some days it takes a little while to get hot and some days it happens very quickly. I'm tired of sinking money into the vehicle but as a recent grad I don't have the money for a new truck at this point. Suggestions included heater core clogged, water pump gone bad, fan clutch.

I'm pretty sure I made a mess of things. My Serpentine belt was all cracked and making noises while idling and driving. It was time to replace it. It's a long story, but my auto mechanic told me to drive my truck for a week and then give him a call. Well.... I didn't do that. My battery went dead and I charged it up and it lasted a month. Yesterday, it wouldn't start so I bought a Serpentine belt and installed it. As far as I know, I didn't damage anything while I was working on it.
The battery was still dead and I charged it, however, the key was turned on while I was charging it. I don't know how I did that, but I did.
The problem I'm having is that the engine is now idling at 2000 RPM. I scanned it and there are no codes or pending codes.
Today, I went out and drew a diagram of how the belt is routed and it's the same as the diagram under the hood. I had a friend take a look at it and he agrees that I put it on correctly.
At first it wouldnt start without me burying the throttle, and wouldnt stay running if i took my foot off the gas, i replaced the throttle position sensor and it starts with no issue, but now if i give it any gas, it shuts of, unless i let off the gas very slowly, what do i do?
View 7 RepliesI have a 99 dakota. The truck wont turn over, headlights/doom lights nothing in side works. But when i open the door the glove boxes starts making a clicking noise ? it happened once before and once i pushed it down a little drive way everything turned back on ? What could cause this problem ?
View 3 RepliesSince we bought this car, it has had an issue where, after it warms up, it begins making a noise which I've seen described as "moosing" on the internet. In addition to the sound, the idle will decrease and will sometimes kill the engine.
I've seen this attributed to the IAC, and so I replaced it (twice). I have tested the IAC connections as well, and all is good. I have even run the car without the IAC plugged in, to try to reset the computer, to no avail. I feel like I have eliminated the IAC from being the problem (but maybe not.)
I have replaced the PCV valve.
I have replaced the water temp sensor and the thermostat (someone suggested this might affect the computer and rpms...)
I have cleaned the MAF and tested it per the Chilton's manual. (tested fine)
I suspect that because of the idle and the engine seeming to be choking out when it dies, that there is a vacuum issue somewhere. I just don't know where to start with this.

View 1 RepliesMy dad has a 2001 Dodge Dakota extended cab with a 3.9L v6 (standard transmission). It will start and run for a while and it will die, if you turn the key it will start up again but will eventually die. He has changed the spark plugs & wires, the distributor cap & rotor, the MAP sensor, and the throttle valve sensor. It still does the same thing.
View 1 RepliesSo, my oil light comes on after startup like usual then shuts off. Anywhere from 2-5 minutes of the vehicle running light comes back on and does not shut off unless I restart the vehicle. Have changed oil pressure switch and oil pressure is reading in the normal range..

I have had this truck in 3 different shops and none of them could figure it out. The codes say misfire in cyl 2 and 5 bank 1 too lean and primary and secondary circuits malfunctioning for ignition coil. I've replaced the ign coil cap, plugs,plug wires, rotor, pcv, fuel pump, pick up coil, cat, o2 sensors and all sensors under the hood. Switched out all vacuum lines, cleaned the IAC and checked the pulse ring. The truck loses all power and either dies or backfires and regains power randomly. If I drive at night, it will stall and keep cranking when trying to restart. Usually have to let it sit for ten minutes for it to turn back over. Last night it backfired and stalled every 50 ft for over a mile. During the day, it revs up and down at idle by about 100 rpms.
View 6 RepliesHave 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).
