If the plug fouls repeatedly, it is likely a bad spark plug wire. Could also be a bad coil or ECM. Could even be a combination. Could also be a throttle calibration error, if both plugs foul. None will leave a code behind. The tech needs to learn some old fashioned mechanics.This past week I had a plug that was fouling and they hooked up the computer to it and got no codes. The mechanic told me that he had seen several RT's that were fouling their plugs. He suggested to me that I switch to NGK KR8BI. I'm due a maintenance for 3000. He said he would replace them then for me if I bought the plugs and brought them with me. He also mentioned to me that if I moved my spyder by starting and moving it and then shutting it down before the motor warmed up, it would possibly cause the plugs to fail due to carbon buildup.... I don't move mine around the garage that way. Even though my plug fouled, it corrected itself and I continued on.
The new plugs are $10-$20 each depending on where you purchase them. I'm going to try his advice.
