No signal from MAF
My 5.3 developed sort of a hiccup on the way to work tonight. I just reconfigured the air intake, but I don't think it changed the positioning of the MAF sensor much. I have a reading of 0.2 lb/min almost all of the time, idle or 3000 rpm and occasionally spikes to 60+ lb/min then back to 0.2 lb/min. If the MAF is dead why does the engine still run? Is it dangerous to drive it much with out it? I found some values to check for on the harness, but the wiring seem to be in good repair. I have never really paid much attention and this issue has made me curious. What type of readings do you all get at idle and at cruising rpm?
