I have a VW golf 1.4 YR: 2001 with 64,000 miles on the clock. over the last 6 months an intermitent problem has occured where the engine revs independantly!! particularly when the car is being driven in lower gears? the engine sometimes cuts out when I am driving it ?!?!

I have taken it to Garages and the diagnostic never pick anything up??? The garage have changed the Lampas sensor and fitted a 2nd hand ECU.

But i still have the same issue and the garages I go to dont seem to have a clue???

does anyone have any idea what this might be or had the same problem or suggest how I resolve this problem??

Cheers S
