help needed
help needed ok i need a little help
I have a 95 Z28 A4 and i'm getting the code for EST ground (42). The car shakes at mid to higher rpms (above 2k) and backfires.
what are all the things i should check to solve the problem.
i've changed plugs, opti, plug wires,fuel filter, and the fuel pressure is good.
The ICM and the Coil also checked out to be good.
any ideas would be great
Thank you
