Went to start my car at my job, didnt let warm up so it was still hesitating from the cold start. I had to move it so i didnt have time to let it warm up and i put in in drive and moved a few feet and the ses light came on. Parked somewhere else and turned the car off. went back later and the light was still on. next day i drove to new york city from virginia and it drove just perfect there and back. had time last night to take to my mechanic and read the codes, as i started my car up, no more light. i take it there anyway figuring the codes were still stored, and his computer read misfires in several cylinders. I have added a picture of his computer screen i took. the car has been driving fine since then.

What could be the cause of this and what does anyone recommend i do now so i wont have problems in the future?

Most common cause of misfires: plugs, coils, injectors. I would start in that order. Swap coils to see if the misfires follows.

The ECU has to detect a series of multiple misfires before it will trigger the SES light and store a code. It sounds like it was a temporary thing related to a cold engine and fuel delivery. Don't worry about it. If it is a coil, plug, or injector going bad, then it will show up and keep the SES light lit, then you can diagnose it.

Thank you. Since then, ive been letting it warm up and letting the rpms drop to 600 and then driving it havent had any lights on since.
