After a moment of rage, and a backwards burnout with the traction control on, my idle jumps from 500-2000rpm. My short term fuel trims are sitting at 128, and the pcm commanded afr is around 13.8:1. The 02 readings are around .480mv, never higher. They do not switch like they are supposed to. What I dont understand is how can the pcm be commanding a rich afr like that, but the 02 not show that? Im throwing 2 codes, maf circuit a low input, and now 02 bank 1 sensor 1 no activity. no vacuum leaks, no exhaust leaks. Ive put a new maf on, cleaned the tb, and cleaned the iac. HELP ME!
