I replaced the idle control valve on my 97 blazer and someone told me it needs to be reset and that it can only be done by the dealer. Is this true.

If you disconnect the battery for 10-15 minutes, the IAC position reference will be wiped and reset when the engine is run next. Just start the engine and let it run until idle sets to a constant 7-800RPM for cold, 5-600RPM for hot.

Let me give the whole story. I have a code that says high RPM detected. I changed the IAC, TPS, New timing chain, Cleaned the EGR, new plugs, wires, distributor, rotor, cap, Crank position sensor and it still shows the code. It runs great except for at a stop it rough idles for 3 - 4 seconds and then is fine. During the rough idle, the oil preasure gauge is going crazy and then it goes normal
