When motor is cranked go into high idle. Changed air flow sensor on filter housing, throttle control sensor, air charge temp. sensor,
If I am interpreting your post correctly, you are telling us that after you start the engine, it idles at a high speed. Is that correct?
However, you did not tell us the actual RPMs that the engine is turning at, or for how long it idles at high RPMs.
We also need to know the ambient temperature when you observe the high idle speed. (Does it do this only when the ambient temperature is fairly cold, or does it do this in all temperature ranges?)
Does it do this only after the car sits for a few hours, or does it also do this if the engine is restarted while the engine is warm?
I am giving this thread a bump, in the interest of getting a response from the OP.
GNB–If you respond to my questions, we just might have some helpful answers.
