Check Engine Light 97 Avalon
Took my car in to the shop because it would occasionally rough idle at stop lights. This was intermittent and would stop by the next day. The shop did a tune up at 81K miles and no rough idle for a few weeks.
Earlier today, I filled my tank and tonight more rough idle at stop lights AND the check engine light came on. I'm going to break down and take it to the dealer tomorrow.
Any ideas on what could wrong? I hate surprises.....
