2006 gg sm 450 fse tps
 

Hi Guys,
Have a GG SM 450 FSE 2006 with what seems to be the usual problems with low idle and cutting out. She starts great but idle is too low and cuts out at traffic lights and such. I can keep her running if I give it throttle. When I explained to a mechanic that I get no response from brass (idle?) screw on throttle body he informed me that if the TPS was not working then turning the brass screw would not work. Does anyone have the part number or replacement for the original TPS so I can get one?
Cheers
Leeman
