Does the CEL come on for a few seconds when the ignition first is switched to RUN?

Have you attepted to run the KOEO PCM Quick Test?

Do you have the service CD? It has a complete diagnostic procedure for this exact fault that will wlak you through the diagnostic and keep you from wasting parts and money.
