Hi all,

I fitted a new MAF & reset the ECU friday night and all was ok.

Started her up this morning & when cold it ran really lumpy as if over fueling...

I fitted it straight from driving home from work so engine was warm.

Could my ECU still be learning the new MAF output settings or maybe another issue temp/O2 sensor ?

Thanks,

Sorry, car is a Std UK Turbo MY00
