Hi all,
A couple weeks ago my car wasn't starting so well, seemed like it did a "mini sputter" before it turned over, so I got a tank of high test (I usually get mid-grade) and tossed in a bottle of STP fuel injector cleaner to boot. Shortly there after the Check Engine light went on, I didn't put 2 + 2 together at first, but the code read out "slight air leak" or something like that, so I am thinking gas cap now, have any of you had issues with FI cleaner messing up your gas cap valve?

Thanx,
