I have an 05 mazda3 hatch that is my baby, I haven taken super good care of the car but recently the check engine light came on and started flashing. My car is idling on extremely high rpms, and I don't get a lot of power when I get onto the gas. It has a new clutch, a new air filter, new spark plugs. I am not sure what else it could be, it started acting funky right after I got gas so I'm not sure if i's bad gas or what, but I wouldn't think the check engine light would flash and it would run so rough. Any other suggestions?
