Hi..

I am having a problem with my mk4 golf 2l gti..

every now and then the engine rev's are sticking/ goin higher when i take my foot of the accelarator or push the clutch pedal down.

The only way to stop this is to pull over and turn the engine of and re-start (which takes forever and when it does re start there is a strong smell of petrol)

Any idea's what this could be as its happeneing more and more often??
