About to run my '87 Carrera (w/turbo) off a cliff - still surging and backfiring
So, I replaced the Idle Microswitch and now an Ariflow Meter. The car still backfires, hesitates, surges around 2000RPM or lower - especially when taking off from a stop.
Idle switch test - wasn't getting continuity at the DME harness plug pin, but was on the WOT switch
Airflow Meter was not gaining voltage in the first 5-10 degrees, then about a .3 or .4 jump in voltage.
Both I obviously thought were the problem.
My multi-meter testing was not fruitful!
Results though, at the DME harness is that every sensor is testing within ohm range or continuity.
My car has a Protomotive chip for the turbo, the only mod done to the DME.
So, ischmitz, Loren, Wong, or anyone else, is it time to tear into the DME?
