My Nissan Nerva 2000, started dropping its idle slowly over a cupule of days to a point where i had turn up the idle screw back up to 700 RPM, when the car is warmed up after driving for about 20 minuet's it would give a bit of a misfire while siting at a red light but then come good on acceleration, it only happens when the car is warmed right up..? No vacuum leaks, Throttle body is clean, Could it be the idle air control valve..? Or a faulty TPS..? My car has a 14 pin port, I've been to three mechanics for a diagnostics test and they don't have the right scan tool for my year model, And it never fails when a mechanic takes the car for a test drive, Well the bloody thing doesn't miss a beat. I guess I will have to try changing both.. Also no engine check light comes up on the dashboard..
You guessed right, Idle air control valve, but you have to also look at your ignition systems like the spark plugs, and ignition coil... in most cases when cars idle low when engine is not heated up, it has a lot to do with the ignition coils and or spark plugs as well as dirty idle air control valve. If you can get a scan tool, then try scan it for codes but I believe the solution lies those 2.
This component can cause it however if you want step by step, watch this video, if it didn't solve is more I will recommend that will solve it when you don't watching the video ruclips.net/video/2-uge5TTfsw/видео.html

My engine check light come on
I being experienced those symptoms with my car Mitsubishi outlander sport without the check engine light. What can that be
Sometimes the car problem might not illuminate the check engine light, what you should do is scan the car and get exact dtc trouble code.
I did all that, I clean the throttle Saturday and so far is been good. Thanks
