af's are below 10 all the time...it'll run alright for a few seconds then just goes to 10.0 a/f's. i can rev the car and all (no missing) but when i hold the throttle steady anywhere it'll start breaking up(and the car is just poofin out black smoke). there is no false rev limiter which i've read a lot about when random sensors go bad the car will only rev so far...i revved to maybe 6k or so and it built boost on the rev. pretty sure it's not being caused from a vacuum leak. if i unplug the map nothing changes? i thought i read when testing the signal wire from map at atmospheric pressure it should be around 2.5v, mine reads 3.47v. when it was runnin i was tryin to check voltage and when i'd touch the test lead to ground to read voltage it's like it would take the signal away and the car would shut off...which kinda makes me think it's workin if screwin with the signal changes how the car runs....i've tracked all the wires and all the damaged wires have been replaced...so it's either a bad sensor or ecu...just having trouble finding info on specs for each sensor...sorry for goin on forever but figured i'd throw out some info to keep you from askin questions i've already tried.
