just got an oil change 3 days ago, everything was fine.

started up my car this afternoon and it was revving from 1k - 2.5k for a while. it's NEVER done that before so i knew something was up. i eventually just drove off and about 5 minutes later at a red light my check engine light came on. i stopped real quick and checked the gas cap which seemed to be on correctly. i made sure of that. turned back on the car, and the cel is still on. this just happened about 5 minutes ago so .. i'm probably gonna take it to autozone and have them test the code real quick. but wanted to first see if i could get any suggestions if anyone has experienced this same formula of events

any comments appreciated

thanks
