Re: (16v) CIS-E idle/mixture problems.

[Emm Dee Emm Eh <scirocco86@home.com>]

The problem is, as the car warms up the idle gradually climbs to about
2000 rpm. I've tried about three different idle valves(the air regulator
valve thingie that buzzes :) ) The o-rings are new, and the car used to
run fine.... I really can't figure this out. I'm thinking one of the
goofy ass temperature sensors is dead, and the mixture is off. *ANY*
help is appreciated.

P.S. Worst case scenario, anyone know a decent CIS guru in the maryland
area that is reasonable?
