I have a 95 s10 2.2 4 cal and I have put everything on it and today I put an ignition control module on it and it starts and runs smooth til it gets warmed up then it starts backfiring.. HELP PLEASE
The new parts I put on it already are a new fuel pump, spark plugs, starter,coil
packs, crank sensor and ignition control module....
Have you checked fuel pressure? And check the timing gear, they are bad about the tentioner breaking.
