Dealer just called... He checked everything (wiring harness and all) and the only thing he thinks it could be is I need a new EGR valve and gasket. They apparently share the same wiring that is causing my TP sensor code and Mode Switch codes? But he said that he is taking an educated guess, because the VX is running fine again.... arghhh

I am hating to spend 300 bucks to replace the valve that might not even solve the problem. He said I can just drive it till the EGR goes if that is even it. Anyone have any suggestions? I gave the ok to go because I need the VX back.
