1995 Cirrus 2.5L stall condition

1995 JA 2.5L intermittent stall condition.At stall all sensor data on DRB is normal.If key is not cycled, vehicle will restart and show incorrect data (lowps) on MAP.Baro is normal and voltage is normal. The PCM will show no change inmap from start to run. If you cycle the key off for 1 or 2 min beforerestart, the code is cleared as if never there, the PCM resets to 0 andthe DRB reads all normal again. This complaint has been ongoing sinceJune of 05. At one service visit the vehicle stalled and would notrestart, replacement of the distributor/coil resolved the no startcondition and it did set codes for this repair. It did not resolve thestall condition. PCM, Crank and map sensor, Idle motor replaced,overlays ran with no effect. ADS is up, will still stall with VSS pinremoved from PCM, Trans controller disconnected, ABS controllerdisconnected. Overlay on 8 volt distributor ground to engine blocksplice (it does not ground in PCM) with no effect. The only way toduplicate the loss of ground or transient voltage spike that wouldcause this, is to interrupt the main PCM supply or ground, we can dothis and it will mimic the same condition, including the key cycle/clear the code. Overlays on every ground or reference voltage we canthink of have no effect, eliminating ignition feed, no effect. Anythoughts or similar strange grounding problems that could spike the 8volt reference and trick the PCM into thinking it is being programmed?Another direction maybe? A Mopar claim on a second PCM?Thanks,Steve

Steve,

Did you ever resolve this issue? If so would you mind sharing what the resoloution was? I'm in the midst of trann/sensor problems on my 95 Stratus ES and would love to hear what you managed to narrow this down to.

Thanks! Richard Ahlquist
