hi all i have been having problems for a little while with poor running on my 2.2 petrol. about a week ago i put my code reader on it and it came up with little or no signal from the MAF sensor so i have changed that cleared the code and fired it back up great no engine managment light but was running like a bag of spaners revs jumping all over the shop anywhere between 400 and 1300 rpm and if i put my foot on the gas it stalles however after leaving it running for a couple of min the revs even out and she tickes over ok and reves up ok but when out for a drive seems very underpowered and after a while put the engine managment light back on so once back home i pluged the diagnostic back in and i now get fuel bank one fault anyone got any ideas before it costs me a fortune at the garadge regards mark
