FYI...
So my car would have a somewhat erratic idle on cold starts. Never had an issue once it got warm nor did it ever bother me. Went on like this for a year and finally threw an SES light. Dealer replaced the ICV and the secondary air mass sensor. Engine is stock except for a dinan pulley.
I also had the yellow striped performance steering wheel and the dye on the yellow stripe rubbed off. I bought this before the blue stripe wheel came out and what wrought with regret ever since.
So guess what? Dealer replaced with the blue striped steering wheel!
Concours has been a pretty easy to deal with dealer thus far!
