Is yours a mass air car?
If so:
1) Disconnect the battery (and the IAB valve) for 20 minutes.
2) Reconnect the battery (but not the IAB valve), start the engine and adjust the idle.
3) wait 2 minutes, connect the IAB valve, turn off all accessories, start the engine, let it idle for two minutes.
4) Shut off engine for two minutes.
5) Turn on all accessories, start the engine, let idle for two minutes.
I don't know if this works for Speed Density cars.... Not sure but I don't think so!
