I adjusted my right rear camber from positive and tried to come close as possible to zero but now my EPC light is on and my steering wheel is turned right when wheels are straight. Does anyone have any info on this or what to do? thanks.

When messing with the alignment, it can and will cause the steering changes. Why are you going to 0 camber? Going away from the factory settings on a street car can cause wear issues on the tires. In order to get a correct alignment, you will need an alignment done on an alignment rack. Messing with it out in the driveway is not the way to go. I think the rear camber on most of these cars is bit over -1 degree standard.

About the EPC light. Where you able to get any codes from the ECU?
