valve gasket cover repair done on Friday. check engine came on Saturday. auto zone did a diagnostics came up with fuel injector system. light went off. came back on Sunday. what is going on with my car? I will be taking it back on Monday. can i drive to work until then.
My guess is that a connector is not back in place or a wire got damaged during the valve cover work.
take it back to auto zone and get them to check it . They did the job so get them to fix the problem .If it wasn't happening before you took the car in . They need to scam the computer and trouble shoot the problem .
