Evening all,
The last couple of days I've occasionally had what feels like a misfire under light throttle when pulling away. Tonight I also had it whilst cruising at 60mph. The loss in power is only a split second - exactly like when you lift off the throttle and slap it back down again.
Suspecting the MAF maybe at fault I disconnected it and went for a drive. It was noticeably worse with a definite vibration and numerous misfires/pauses. It didn't throw any dash lights.
My mechanic kindly hooked up his diagnostic machine and saw that there was only 1 stored fault, something to do with the throttle position. We went for a drive whilst it was connected and sods law... the car was fine and no new codes were found and throttle voltage was consistent :frusty:
The MAF was reading 43 @ tickover. He's getting me a new one to try tomorrow.
What's also puzzling me is that whilst searching for this type of problem/solution, everyone appears to think that disconnecting the MAF should make the car run fine - so why was mine noticeable worse?
Any comments/suggestions of what else to check will be gratefully received as I appear to be on a bit of a bad luck streak with a new window regulator last week and new aircon piping the week before - oh, and we won't even mention the oil leak and sunroof showers
BTW it's a 2002 TD5 Auto on 109k. Full major service 4000 miles ago.
