Hi guys 1st gen Matrix XRS (05) owner here. Need to know where to take this machine for some work. High idle issue P0505 CEL, been at the mechanics for a week, they've cleaned, and now replaced the IAC twice (thought they got a bad one the first time) but still 2000+ RPM (higher when cold)
Fuel ratio checks out (within spec) so not a vacuum leak, car runs great otherwise. Just the high idle issue. Mechanic has given up, says to take it to the dealership, thinking it may be a re-flash issue. Where do the is the 2ZZ guru's work in Calgary?
