MY S3's REVS ARE BOUNCING UP AND DOWN only when sat stationary at the lights etc it seems to pull ok although it gives the odd judder whilst accelerating hard
i recently had the timing belt changed but it was fine till about a week later when i dropped oil and changed it for a 5 x 30W
IVE CHANGED THE PLUGS SINCE IT STARTED DOING THIS, ALSO CHECKED THE COIL PACK AND IT DOESN'T SEEM TO BE THAT EITHER, I DISCONNECTED EACH COIL ONE AT A TIME TO CHECK THOSE AND IT ONLY MADE IT WORSE,
FAULT CODE IS COMING UP AS > HEAT TEMP SENSOR AND > IDLE FAULT
HAS ANY1 ANY IDEAS AS TO WHAT THIS MIGHT BE OR WHERE I SHOULD START TO TRY FIND THE CAUSE IM BAFFLED AND DONT WANT TO START THROWING MONEY AT IT??????
