Drove the car again today, seems to be surging a bit, kind of feels like the clutch is slipping only it isnt the clutch (car has less than 28K on it and the revs arn't jumping up) Anyone any ideas? Should probably get this fixed before the remap, could this be throttle body too? MAF sensor is one of the newer ones, not sure when it was replaced but was fitted with the 5 star bolt instead of 6 could be the other way round but definitely a newer maf.
