i have a 92 coupe that is draging at wide open trottle i cleand the maf sensor today got a new k&n air filter new fuel pump straner and fuel filter new spark plugs and new cap and button(MSD). any ideas what it could be?

 

Whats the last thing you did before you felt it start to lag at WOT?

Did it just all of a sudden happen?

 

nothin i bought the car like this i started noticed it about a week after i bought the car. u think it might be the throttle position sensor?

 

ok i was lookin at my engine today and the vacuum line was off the fuel pressure regulator could that have been the problem?

 

uhh yeah, your car was running lean most likely
