I've searched the hell out of this and couldn't find anybody else with the same issue, I was pulling out of chick fil a today and suddenly with no warning my car starts shaking violently, and it feels like its coming from the engine. When I start to accelerate and reach 2500rpm and it starts going crazy and bliping the rpm needle up and down not wanting to go past 2500rpm. It's not overheating but the temp guage is starting to rise. The service engine light also came on at the same time and is steady and not blinking. I filled up right before with premium gas from a 7 eleven just before and I checked my gas cap and it's tight. Any suggestions?
