My car drives fine in the city and on the highway. When the engine is cold or cool it will idle normally around 800-1000 rpms. Once the engine is warmed up to near the half mark on the temp gauge in the dash the car will stall or try to stall if idling for one minute to five minutes. The rpm's will drop to 500-800, engine will shake, and either stall out or surge up to 1300 rpm's before going back down to 1000. When the rpm's are low if I press the gas nothing happens or the car stalls out immediately. This only happens once it is warmed up. I have consistently let it idle for fifteen to twenty minutes when cold and no problems. Sometimes I get a very light white-grey smoke from exhaust for a couple of minutes. A quick note it always starts right back up after stalling.
This has been going on for a couple months. I am getting no error codes. Short list of things I have tried:
Replaced Camshaft Position Sensor.
Replaced Throttle Position Sensor.
Replaced IAC Valve.
Replaced Spark Plugs (one had a little oil on it).
Cleaned Throttle Body.
Replaced PCV Valve hose.
Cleaned EGR Valve (had a fair amount of carbon build-up).
Transmission fluid level is good.
Replaced Air Filter.
Oil level is good.
Coolant level is good.
No fluid leaks.
