check engine light and cruise control light
Check engine light on and cruise light is blinking, took to reputable repair shop and tech said car was running rich and ECM pulled code for rear 02 sensor bad,Ok'd repair and 2 days later both came back on. Should I be concerned that ECM they have might only show a fuel related problem. I certainly don't want to start throwing parts at this. Should I take to dealer service or ask tech if he pulled exact code, Or do you know what possibly could be wrong? Any advise or answers would be greatly appreciated. Thank You
