oxygen sensor

i recently had extractors put on my EA, it ran sweet for about a week. 125kw dyno'd. one day she just started being really jerky stalling in neutral, running lumpy and spitting and sputtering when revs were returning to idle. the last week or so she has backfired a couple of times. i took my car to turbo tune 4 times, they diagnosed that the oxygen sensor was faulty, so i bought a new one. this did nothing. they changed my ECU, this also did nothing to fix it. i found disconnecting the O2 sensor fixes it, but it uses a full tank of petty in bout 100km when disconnected. two other places couldnt find the problem either. Can n e one help me??????

Re: oxygen sensor

The hose may have come off the map sensor if its backfired, or the map sensor may even be faulty.

If all that is good, then move on to the coolant temp sensor as this can also cause that fault.
