Like the title states. I have never ran into this before. Procharged car, 80lb/hr injectors, tuned like I have several others. Even forced OL and o2's unplugged, it will idle at 1.00 lambda for about 30 seconds, and then the STFT's will start hammering it with fuel. The log attached shows +99% STFT. No matter what I do in the Oxygen sensor tab, or the Closed/Open Loop tab, the car does the same. Log attached shows unplugged sensors. Sensors plugged in read around 0.750v at idle before it starts slamming fuel in it. You can see that target lambda changes as well. Any ideas would be greatly apprecitated.2v Runaway STFT.hpl
