Just replaced the MAF sensor due to confirmed inoperable sensor and now my engine started to rev by itself to approximately 3,000 rpm's for about 2 to 3 seconds then smooth out to a nice idle. Doesn't do it every time. Reset the ECMC by pulling fuses and battery and that helped immensely with other weird behavior including A/C compressor not kicking on. But still self revs from time to time. Could this be the ECM relearning the new sensor? Or indicative of something else such as TPS or MAP sensor?
