My car has been running nice for the last few weeks, except for a strange movement in rev range every now and again. I thought it was a cold start issue, but it happened on my way home today when the car was at normal operating temp. It's not a major issue, but basically the car just slightly revs higher or lower without making a big enough change to display movement on the tacho needle. I'm guessing we are talking less that 100rpm, but enough to feel it in the pedal. When franz performed a conzult on my car last week the TPS seemed a little high, but my idle was fine so we thought nothing of it... Any suggestions of what it may be, or how to resolve? Cheers Paul
