Question about 2000 Dodge Dakota Quad Cab

Warm or cold, my 4.7L V-8 jumps up to 1,500 rpms every time I start it. Then it immediately settles down to 600 rpms. I have replaced the TPS sensor, but the problem remains.

None.

One thing you can do yourself is remove the fresh air hose from the throttle body open the throttle use a soft towel and clean the butterfly valve and throttle body then disconnet the battery for a full two minutes when you restart the computer will do a idle relearn and may be hard to start for a few minutes and might stall this is normal for the relearn once a stable idle is reached drive vehicle for several miles you may still experience random idle surges as it relearns base idle strategy but should return to normal within a day or so of normal driving most of the time only a few minutes are needed but once in a while it can take longer

SOURCE: dodge ram 1500 engine rpms surge at freeway speed

those sensors could cause the issue, clean the MAF 1st, also clean the idle system using the following procedure, the IAC can cause cruise surge. I use this to cure these problems all the time.

Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve (IAC) and throttle valve, they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

1969 with 351 Windsor stock engine. Once it reaches 1,500 rpms why do the tach & engine jump up and down?


If this is a points type ignition, check for excess play side to side in the distributor shaft, and also for timing chain slack--easily tested by removing dist. cap and rotating engine back and forth with wrench on crank pulley bolt. If rotor doesn't move immediately as crank turns you have loose timing chain.

Why does my truck move slow in the morning and when sit for a time and then picks up speed after. Then idle jumps around at1500 rpms up and down then it settles.


Does the engine rev up when you press on the gas or bog down?
Do you smell a funny smell when the truck is running?

Chevy Malibu Cold Idle Problem


Check the water coolant thermostat. If it is stuck in the "open" position you are heating up all the water in the coolant system and this will take time. The thermostat keeps the water in the engine until warmed up to almost normal running temperature, only then does it allow the coolant to enter the radiator.

Have you tested the IAC (idle air control) sounds like it's sticking, I have tried to clean them but it was short lived, so once you have determine it's bad (after market $85) I would replace it and solve the problem.
