Folks,
I'm trying to hunt down a surge/misfire with my car. 92 VR4 with 93 engine, no CAS, and 99 Jezters ECU. When cold, the car runs ok. Once it gets hot it surges badly and seems to misfire. On a few cold starts, I hear a rapid clicking noise from the ECU area. At idle if I hit the gas, the clicking seemed to increase. I beleive this ised to be a sign of ECU failure in the early ECUs, but do the Chrome ones have a similar issue? Does anyone still repair/support them?
Possibly unrelated, but I also get a random P0120 Throttle/Pedal Position Sensor A Circuit. (The TPS was a brand new OEM unit). I have removed and tested the (New) TPS and it seems OK. But that error does come back even after adjusting the TPS.
Hoping someone out there has an idea on these..
