Evening all
I visited a friend in Gosport (Hampshire) this yesterday afternoon which allowed me to clear the cobwebs out of my mk3 1.8GL on the M3 and M27, which i think did it some good as i've only been doing short journeys of late. On my return up the M27 and M3 all was going well until i came off the motorway and drove at a steady 30mph, and after about 10 minutes of travelling at this speed it started to "Kangaroo". I managed to pull over and turn the engine off hoping that this would cure the problem, which it did the last and only other time this happened which was over a year ago.
After allowing the car to cool down a bit i checked the fuel injector connections and almost all others whilst i was at it, started the car again and it was still idling erratically which to passers by must have looked like i had just passed my test or had stolen the car. The car is serviced on a regular basis and was last done about 3 months ago with the timing being adjusted and a couple of other things as well, and has nothing serious go wrong with it todate.
I was stumped and 2 miles away from home on a Sunday afternoon, so the only thing left for me to do was to call the RAC and hope that they can give me a hand. I was informed that it would take about 45 minutes for a mechanic to arrive which is the norm, but it took more like 10 minutes which was a pleasant surprise. I explained what was happening and after a number of things were checked it was determined that the Throttle body potentiometer was the probable cause of the erratic revving.
Is this something which i could personally replace if so where can i get one as GSF don't seem to stock them, or do i need to visit my local stealership.
Cheers guys
Antony
