My RR is misfiring on about 5-6 cyl. I just paid 310.00 to have the spark plugs replaced, and that did not seem to rememdy it at all. The shop then tried charging an extra 400 to replace the wires. I said no, and left. I want to change the wires, but with that many misfires, I am thinking it is the coils that need replacing. The trouble codes I got were: 1300, 303, 300, 302, 304, and 307. Can someone please shed some light on this?Thanks!![/align]
