Question about Pontiac Firebird
Service Engine soon light is on. Just had a new radiator, mass air flow sensor,and gas tank put in 4 months ago as well as new gaskets and maybe a fuel injection pump but I have to check. My car will reverse fine but will not excel over 20 mph then the engine completely cuts out. When I try to restart it, it just sounds like it's going to die again. Any ideas as to what's wrong?
Ttry the coil packs I had the same problem. To find out pull one spark plug wire at a time and lay it on top of the coil pack were it was taken from and see if it is arching.
