2008 Porsche Cayenne GTS 4.8L Misfire
Posted to European Driveability on 9/19/2017 4 Replies

This car came in with a P1023, P0302, P0303, P0306, P0307. Car runs rough under load around [...]. I can't imagine 4 coils going bad, was thinking a software reflash or a fuel pump. I don't see many of these cars and would appreciate any help.
