[QUOTE="ain'tstuckjustresting, post: 1434816, member: 18302"] But sir IAC is not a "sensor":kissmyass: This thing runs like shite in open loop so I doubt the O2 sensor is causing this I have no way of reading IAC counts w/o a scanner, Input voltages are right on 5v for the TPS,and MAP Didn't read the ECT but when at op. temp it sends 1.7v to the ect signal pin the sensor reads 231ohms at 190deg which seems pretty close. Didn't check o2 voltage but ran it unplugged and saw no change if performance. Forgot to write the MAP signal down while running poorly but with the metered vacuum leak and decent running it reads 1.2v @ the ECU. I've got **** scribbled all over this damn pcm symptom chart.
