Default Flashing SES....

Ok the only thing that had been changed before this happened was going to true duals. My SES light started flashing the other night so I took it in to Auto Zone today to have them read it, all they came up with was 2 EGR codes and 4 Multiple misfire codes P0300 he said. Would a P0300 cause the SES to flash?? If so I know I've had misfire codes in the past because of the cam but the SES has never flahsed before. The car drives fine no problems at all. Any idea's????

the flashing ses is due to misfires - the system warns you that if not corrected it could damage the cats. Has the code or ses returned since you reset it?

This is common with an aftermarket cam. The P0300 should be turned off in LS1 Edit, or have the misfire values increased in the tables. And yes, it will make the SES flash.

Thanks for the reply's guys. I was just wondering because I've had the misfire code show up before but the SES has never flashed until now.
