dusty_mauve 0 Posted June 12, 2005 Report Share Posted June 12, 2005 When I press the trottle and idle the car at 1500rpm it won't hold the revs at 1500, it dies back to about 900 then flicks back to 1500, and continues to do so. It idles fine with no throttle application and at 2000 and above it sits fine too.When driving and the revs are around the 1500 mark it decides to come off throttle slightly, like it's dropping out slightly, then comes back on. I've had it on VAGCOM and it's showng no faults. It's not down on power ar anything...Can anyone shed some light on this for me?Ta Link to post Share on other sites

dusty_mauve 0 Posted June 12, 2005 Author Report Share Posted June 12, 2005 it's been suggested that it might be due to an air leak, I'll investigate that too tomorrow Link to post Share on other sites
