I just bought my STi today from a private seller and on my drive back home I passed some old guy and my check engine light came on and my cruise is flashing. There are no after market mods done to it yet. There is a factory short throw installed, if you wanna call that a mod. It has just under 13000 miles and with the CEL and flashing cruise it's still running strong. HELP I don't want to ruin the car or it be a lemon!!!
