Evening gents,
Strange one here, it appears I've gained someone else's problem...... Corsa C usual misfire fault codes of P0300 & P0301, car starts & runs fine for 2 minutes or so then starts to miss ??? looks to of had a new coil pack, plugs, fuel filter as though someone has had a crack at this already ? So to start from the top:

Number 1 injector is being shut down by the ecu(CAT protection), prior to this has good waveform & correct operating parameters. Coilpack peak voltage checked, around 25Kv. Now i'm aware of the water in fuel situation these suffer so i have checked that to no avail ! After continued diagnostics i found that if i run the vehicle with the EGR disconnected the fault (misfire) does not appear ???

Not sure i'm not overlooking the absolute obvious here so any input is appreciated.

Andy
