Can anyone ofer any help with my Golf GTI the engine will not rev as cleanly as it should, it feels like it has no power .
Some times if i just switch it of for a few seconds and then start it up again the problem disappeares and it pulls like a train and revs as it should.
This problem is seems to be slowly getting worse, i have tried the obvious things like new leads /plugs /distributor cap/fuel filtter/ and so on
also i have checked any obvious wires for breaks etc
any ideas anyone
