This car was running great, all of a sudden started it one day and very rough and would stall, ran at highway speed. Was giving camshaft sensor code and multiple misfires. Replaced camshaft sensors, no change. Replaced vanos solenoids, no change. Replaced both Disa valves(these were clearly bad) car ran much better but still rough at idle. Giving misfire codes and p013b code. Unplug coils one at a time and no change in the way the engine runs. Help!!!
