Ihave the dreaded miss - optispark?

Unfortunately, I've had to park the vette outside for the past week. While it hasn't rained, there has been some morning due. Anyways, yesterday I decided to go for a spin (it's not my daily driver) and to fill up the tank. After I filled the tank, I noticed a low rpm miss. It was fine in the mid-range and upper-rpm.

However, this morning as I'm driving to work, the miss became more pronounced; low-rpm, mid-range and upper-rpm. Also, the "service engine" light came on. Is my opti taking a dive? The car only has 36K miles on it. What do you think?

I think you should start saving $$ for a new opti. Sounds like the symptoms mine had before it died altogether. That was at 78K miles.

Since you are in California, rush to the dealer and suggest that investigate the opti. This is covered for 7 years and 70,000 miles in some states, California being one of them (that is how I got mine replaced last time).
