this sounds like a problem with the ECU... I can never remember the next part... but when the engine is cold it runs in open loop(I think) and uses tables to determine mixture... once it warms, it is in closed loop (I think) and uses inputs.
if a part is throwing a code, make sure it is bad, or, if the circuit to it is bad.

Re: MY vette WHY!! (SLEV89)
This derned book I have shows a code 36 as an ignition system circuit error, and a code 34 as a MAF circuit or transaxle shift problem? I think this thing needs to be thrown in the dumper. Nothing else in this thing makes any sense either :mad
