My step son is the one who has the car and here's the problem. He had some sort of problem with the car and had a friend haul it home for him and when they unloaded it they let it catch on the wagon and it messed up the exhaust pipe and he had to have a section of pipe replaced at a reputable repair shop, Now he can be driving down the road and suddenly the display will show engine power loss and the car loses power of course so he has changed the battery he has removed the catalytic converter he has replaced the throttle body and gas feed position sensor the map sensor the mass air flow sensor the gasket under the EGR valve and had that tested, the only way we can get the car to run like it should so far is to unplug the new mass air flow sensor that we installed. The car will display the engine power loss and then if you continue to drive it it will idle up and down up and down. when we unhook the MAF sensor it will smooth out and seems to gain back the power. Any thoughts help or ideas would be greatly appreceiated!
