so my car has good spark and fuel pres. reads 45 psi. but i notice that my exhaust is really quiet on startup and when idleing. car does idle at 900 rpm. i have a dc posts exhuast and i kno its louder than it is sounding now. as soon as i apply any throttle it dies.it does have the stock cat on for now i think its all jammed with carbon deposit or somethin bc it is the one that came on the car in 2000.i have ordered a test pipe but i wanna hear some opinions i kno my engine isnt blown for sure bc it was jus rebuilt and i did a compression test yesterday. no gaskets are leaking or anything.
