Yj 2.5l backfiring problems
I have a 1992 2.5 liter yj and it is back firing and has no power above 2000 rpm. This only happens when the Jeep gets hot. If I shut the Jeep off for a minute and start it back up it’s fine for a few miles.
things I’ve replaced:
Spark plugs, wires,entire distributor, map sensor, intake air sensor, temperature sensor, map sensor, fuel pump, fuel filter, air filter, thermostat, coil, o2 sensor, removed cat and new muffler, crankshaft position sensor, throttle position sensor, idle air control valve, fuel pressure regulator, new ecm.
