O.K. Mia Culpa I Forgot To Put In A Topic ??
sorry ...But I Did Find The Answer to my question which was ,
About the lower plenum and the six butterfly valves ...and if anyone has tried to resolve the problem differently than replacing everything ...

MITSUBISHI and it`s dealers are no help ...but you most likely know this !!!
I have come to find out that an auto engineer calls this system ( OLD TECHNOLOGY ) He said You Can Either remove said valve system or keep them fixed in an open position , they were designed to help with cold air and modulate as air temp changes ....not really necessary on low torque /low powered engines ...there may be some gas mileage changes but these cars are not economy anyway ... thanks for the responce ...Oneonta ,ny city of the hills
