been reading thru all these threads and seen alot of people knocking zzp pcms, unfortuantely i ordered and installed one before i read all this. some have mentioned grenading the engine in one thread and others had mentioned tranny issues.. not sure what is ment by grenading the engine? anyone could clear that up great.. assuming too much fuel. not happy about having to shell out another 100 bucks for another pcm from somebody else but if it means saving the car i better. it's only got 58k miles on it. if anyone can lead me to some real proof not just oh ya you better change it that would be great. also all the threads i had read were old so has anything changed maybe? thanks in advance. mike
