Hello! New to this scanner thing. The OTC 2000 seems rather limited to 1 Mode at a time and not all modes apply to the GN. What modes should I check on this car? TPS, O-2's,Knock,ETc. What would you look for? So far the O-2s seem to indicate rich,the knock says none present,TP stars at .44 and goes to 4.5. I turned the fuel pressure down and it seemed to lowqer the O-2 readings, would that be right? Also if the cars was too lean would I be experiencing knock? Thanks!
