took the car out for a spirited drive at lunch today, got back parked up and didnt go back to the car til after work, bout 3 hours later, went to start the car but didnt start, look underbonnet and one cable had come loose from battery, put it back on and car started fine but when i went to accelerate it was very stuttery (if thats a word) and got worse when turbo kicked in and i couldnt really rev past 4k.

have i buggered the ecu because the battery got disconnected for so long or is something else major wrong.

HELP!!!!

 

anydody help, it sounds like a misfire but what would suddenly cause it?

cheers

 

MAF sensor?
