So I just bought a 1996 Camaro Z28, it seems to struggle to get up to 0-60 which is about 9.8 seconds. There are no codes and the only previous codes were A/C unit. It doesn't feel like a Misfire, but I can smell a tiny bit of raw gas while driving. Cleaned the mass airflow and throttle body, and nothing.
Transmission has been rebuilt but doesn't seem to drop gears at the right speeds. I can be rolling at 35 in 3rd and it will drop to 2nd when having it to the floor pushing from 2500 rpm instead of going to 1st. Any thoughts???
