My service light came on, i got a code scanner and P1320 came up, everybody is saying its the ignition coils so i replaced all six coils with new ones , also replaced spark plugs, didn't notice any damage to wiring but the same code still comes up after I clear it. Also the car runs some what rough at idle and dash board lights flicker somewhat, what could be the problem? Any help would be greatly appreciated...

That is typically the code you get when the coils go bad. After they're replaced you have to clear the code. Leaving the battery disconnected for 12 hours will do this I believe. Make sure your spark plugs are gapped properly.

Go to and search under P1320 and you'll find tons of information.
