service engine soon light

I have a AMS Custom reflash and have had it for about 9 months with no problems at all. Ive done no mods sence the reflash either. well all of a sudden I got a service engine soon light and had it checked to see what code it was throwing. It said it is a random cylinder miss fire? any ideas? I changed my plugs and reset it and it went away for about a week but resurfaced last night.

thanks

Was the code a P0300? Is your car an 03?
It tends to happen on certain 03s and some people have success in getting rid of it and others have it constantly.

Hey man, I have same year same mileage. I get 4 codes ALL the time. Misfires and O2 from the exhaust. I clear them but they come back after about 50 miles. It is not worth worrying about. Once you are tuned it is gonna throw certain codes especially from cams and exhaust. Everyone I know has the SES light on constantly.
