OK my car (TTA) will start backfiring hard randomly on the freeway and throws a code 42. When it starts backfiring I see on the tach and scanmaster that the RPMs are erratic. It should be showing 2500 or so but the needle is dropping down to 1000 or near zero.
I have already changed:
ECM
Ign Module
Coil Pack
Crank Sensor
I checked the cam sensor cap and it looked OK but didnt change it.
What else should I try??
