Last tune up was 2 weeks ago - no difference.
Check engine light comes on about once a month while normal driving then goes out on its own. When checking the codes, the last fault is null. T one time a snap on scanner caught a map sensor fault, but that was 2 years ago.
The problem has been going on for about 3 years now. It never happens while in the shop.
