Chaps Got a slightly odd problem. Recently did some work on the car which included dropping and then refitting gearbox (broken quill shaft), dual mass flywheel regrease, new clutch bits and bobs, new thermostat. Put it all back together and now it struggles to idle or pick up on throttle. Runs OK once it clears the initial stutter (say, above 2k rpm). I don't have any OBD equipment to check any sensors but struggling to think it'd be that as none of them have been touched and I can't think which of them wold be causing the issue. It has all the characteristics of an air / vacuum leak (to my mind) so I replaced the idle control valve and checked all the vacuum lines I can see but still no Bueno. Its doing my head in. Any suggestions gratefully received.
