Question about 1990 Pontiac Firebird
When taking off or load is put on motor rpms drop andit seems to have no power i did a commpression test all of the cylinders have good compression timing is correct by the way the motor is a 305 pontiac
Test map sensor, throttle position sensor and mass air flow sensor all influence timing (You are checking base timing only) and fuel delivery. Also check temp sensor as if it's not working the computer will never know when to change over to warm run mode. Is ecm fuse installed and good?
