Hello everyone. I have a 2011 rr sport supercharged. Truck started running bad checked scanner and had misfire at startup, misfire at 1000rpm, misfire on 1 ,3 , 8 I changed the plugs and it ran well but still had misfire code. After several months it started running bad so I changed all the coils. It still was running bad and now I got all misfires ,all 8 cyl, and start up and first 1000rpm I can't seem to find the solution.
