Idle rpm problems

I have a durango with a 318 the tps and idle air control valve have been replaced and now it idles correctly at times but usually sticks at 1000 rpms after driveing long or short distances. if i pop the throttle to the floor while its running it usually sets down to the proper idle.

Check and clean th egr valve or just replace it. Sometimes I have seen that both the EGR and the IAC need to be replaced and sometimes, people only replace one. I personally on my own vehicles when this happens I just replace both at the same time

My 1998 Dodge 1500 Ram with a 318 engine stalls when I come to a stop. This only happens when the engine is warm.


It probably Throttle position sensor and/or the Idle Air Control Valve. If you need more help diagnosing these, please let me know what tools you have and we can go from there. (i.e. do you have a multi-meter? etc...)

High idle after engine is warm. nothing is sticking with linkage.1992 chev k1500 5.7


Make sure the idle screw was not turnned causeing tps sensor to read over the spec limit, the next then is to make sure the idle air control valve is working , a bad valve will cause this problem and last is the stepper motor that controls the idle. some of these around this year used steeper idle control motors instead of idle air control valves and in turn the stepper motor is bad it will hold the throtle plate open to much causing the tps reading to be wrong triggering the engine light to come on. the steeper motor will be boltted to side of the throtlebody and theres a small arm to the throtle linkage. i will enclose a stepper motor picture and an idle air valve to show you, but this sounds like the tps is out of range due to this. the last thing is to make sure there are no vacuum leaks, spray crab cleaner around throtlebody base gasket and also the intake mounting gasket and see if the idle changes is so theres a vac leak in that area. good day. okay just did a little research and this truck does have a idle air control valve, the picture is encolsed and is screwed into throtlebody, check that and for vacuum leaks, make sure tps is good sometime it will test good when testing and go bad when it wants, you could have a bad tps and idle air control valve also.11_27_2011_9_27_54_pm.jpg

What is the correct idle RPM for Durango 1998 5.2 L


Doing the opposite of what it should. Don't know, but the idle should be awful close to 800 on a warmed engine. You may have a vacuum leak causing your high idle. Check all your vacuum hoses for condition and proper routing. Pull one hose off and create a vacuum leak. It should cause your idle to raise. If it doesn't change the idle, there may already be a vacuum leak. By spraying carburetor cleaner around suspect areas, you can also find vac. leaks. The spray will be sucked into engine and change the rpm's.
Other possible causes might be a sensor ( CTS?TPS?) or an idle control valve, or some other computer controlled part.

Throttle/Idle/running problem - wants to run too fast, or stall out


RPM's up and down check EGR valve and sensor. EGR valve and sensor control idle. That's why your getting the surging on rpm's and this could be giving out the other codes. If mass flow was bad car will not start and the same for the map sensor. O2 sensor measures gas and air for right mixer. TPS controls 0-60 speed as in throttle respons.

Fault codes, p0102,p0122,po507


po102--maf sensor, could be a bad air cleaner and not letting air into engine, po122--tps pedal position sensor low, replace or adjust tps sensor,or wiring,po507--idle control system high input. for this you can take off idle air control, and clean out carbon from were it mounts on engine. it is just before throttle body at end of air intake hose, it is black. do not push on pintle on end of valve when cleaning, use a old toothbrush to clean carbon off of valve, use carb cleaner but do not soak valve in liquid of any kind. good luck!!

Idle too high +goes higher when put in gear (manual transmision


IAC valve problem. Nissan has a updated harness (with one way diode inside of the harness) to prevent backfeeding for the IAC valve and a new IAC valve also gets installed. That's where I would look. IAC valve or "idle air control" valve.
