So far, on this car I replaced the MAF (it was reading 2.6 volts key on Engine off) replaced it with aftermarket MAF which reads .2 volts key on engine off. Reads solid 1 V at idle.
In an earlier post I mentioned that many users of the red/blu/blk wire weren't working, well someone disconnected the wiring (maybe PO when he replaced the right side doors due to a wreck.)
I was apparantly driving the car with a bad MAF and no volts to O2 sensors and air pump. Actually the engine was rather responsive in those conditions, running better with the CEL on (with 10 codes) than without the CEL on and no codes!)
Anyway, here's a video of starting and running with the surging. seems like something is oscillating at resonance because the surges become increasingly more drastic until the car stalls.
