SES light.. Place your bets..
Car's been sitting for 5 months, run occasionally but not for long. Noticed I used 1/4 tank of gas today with mild to moderate driving around town but nothing excessive. (1/4 tank useage is abnormal for one day in this car).. Car runs fine, but idle has been stumbling for some reason. It did rain today. The idle stumble is normal for this car when I start it, just gotta let it cough for a second to find it's idle and it's fine. Tuned at 3800ft altitude at TSP. Now at sea level. Runs and pulls fine, no knocking, hesitation or bogging.
Ideas??
I'm thinking MAP or O2's.
