2.8 runs again....

.....kinda, i finally figured out what was wrong with the 2.8 in my 88 RS the coil, cap and rotor were bad, the reason i didnt check this before now was the po had said he replaced them not to long ago. But now the car will not idle until it is warmed up, and when you rev it to fast it backfires into the intake hard enough to lossen the speed fasteners on the air filter cover. Could this be a timing issue or bad ECM or bad idle air or a combo of all of the above. The car also will not go into reverse, it will lunge a little but will not move back idk what is going on. Any sugjustions would be greatly apprreciated.

Keith

Re: 2.8 runs again....

The first problem sounds lean or timing issue. Is it a stick or auto. if it is auto will it go forward in neutral?

it is an auto, and no it wont go forward in neutral. Now has a bag knock in the bottom end of the motor. Probably going to build a new motor.
