I don't use the scoob so it sits all week until a saturday when it gets a drive washed.

Last week the car ran like a dream, sat on idle without any issues, nice and even.

Today the opposite!!! drives fine, but at idle it sits at 2k revs but when slowing down to stop the, still in gear, foot on clutch, the revs drop to normal idle revs.

Nothing has been done to the car, so i can't understand why this is happening?!

Any ideas anyone?

The car is a 2001 bugeye wrx, fmic, apexi induction, Andy F remap.

Thanks for any help.

S!
