Well certainly have me and everyone posted if you come up with something. I pretty much love this car except for this on-going issue, I've dumped thousands into it with no luck.

I actually replaced the sensor. I replaced everything that affects A/F ratio, and then some. I also done some experiments with the ECT sensor by unplugging it and plugging different resistors instead to fool the ECU into supplying more fuel, and it seems that with restance that normally means 60 degree when the engine is actually at 80-90 degrees, the car has much better acceleration, but it pings like crazy.
