Service Engine Soon light came on!

This could be any number of problems. The most common being the O2 sensors in the exhaust. If you have an aftermarket exhaust, they could be burned out or a bad connection. It's best to take it to a dealer and have them check it with their computer, which will locate the problem in about 2 minutes.

Also if I've noticed it you run STRIGHT race gas sometimes the O2 sensors get a "hazed". If you have this may be the case you need to run just 93 for a while and that should clear it up, nor would I run stright race gas in there again, I do half/half if anything.
