If it is ECM controlled engine , there could be a problem with the coolant temp sensor unit not giving the right signals to the ECM
run any fault codes and take it to a cummins shop for a proper diagnosis and quote

2500 HD chevrolet low idle problem


Engine stalling and rough run issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

My 1997 Chrysler Concord idles at 2500 to 3000 rpm when first started and when it warms a little it idles at 2000 rpm and stays there. When I start it right after I turn it off, it starts at 2500 rpm then...


Maybe a short to the TPS or something shorting it out. There's also the IAC that really controls the idle but usually it will cause the RPM's to go up and down a little erratic if bad. The MAF sensor can cause major problems as well but since you already swapped the TPS and it helped and then stopped I would focus on that sensor and especially it's wiring to and from the ECM. Be careful with the sensor signal wire to the ECM can blow it if more than 5v passes or spikes.

Engine stalls


sounds like one of a couple things could be causing you problems first would be the fuel pump may be wearing out. these are a mechanical pump and should be producing over 35psi at the injection pump if you have a way to put a gauge on it you could check this under full throttle is when you want to watch it though. fuel gauges are quite inexpensive and are handy to have in the truck anyway. another thing i have seen cause this is the check valve on the discharge of the pump there is a spring and ball in the return line banjo fitting that holds the fuel pressure at a constant 35 psi when that gets weak it allows more fuel to return to the tank which will let it run at lower rpm's but not under full load. hope this helps

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.
