Running Issues

Hi Folks, please help:

Here's the deal

Replaced turbo with VF34 and sports cat downpipe installed. Car mapped and running tremendously well. Took the car on track 3 days after the map and it was fantastic. Drive home, fantastic. Up the next morning, fuel light on took it to the petrol station and 100 yards from the forecourt, the car gives starts to run lumpy as I appraoch the give way, I think oh no, Im out of gas. I make it to the pump, fill up, drive off, same problem.

Its been running like a bag of spanners ever since, mostly in low revs. Changed the plugs no joy, ran a different MAF was a bit better but still not right. I have spoken to everyone and anyone and can't get a solution. It has been suggested that it might be injectors or coil packs (earlier suggestions were thought to be a damaged ring-land due to the ECU knocking at same low revs, however, it seems that its a misfire that is triggering the KS thus making matters worse).

SO! Can anyone what it might be? I am going to put the car off the road for a couple of days for extensive checks, but would rather avoid that if possible because: a) I NEED the car b) I DON'T need the expense!

Other info that might be of help:
  • WRX MY06 2.5
  • Diagnostics checks show no sensor faults
  • Misfire at low revs (mostly)
  • No smoke or vapour from exhaust
  • Water levels fine
  • Put fuel cleaner in, no joy

might be worth getting it back to the mapper getting them to hitch up the laptop and go for a wuick drive, should be able to see what the exact issue is, if its not fireing right or fuel issue etc.
