Symptoms of an erratic Crank Position Sensor?
Is it possible for the CPS not to function properly on cold/hot starts up to a certian TPS% and then be totally fine thereafter, regardless of idle speed, etc?
A4 Z28, cam, bolt-ons - Car would idle perfect, no misfires, part throttle driving was perfect. When hitting WOT rpms, not until about 5K would a massive backfire ensue, the motor shutoff completely. Lotsa backfires. No codes either, but a CPS swap chased away all that bullshit
