What is up 2020! STILL working on this mf’er. I broke down and ordered the TPS kit from ACT out of GB. Works great but I still have the damn stalling issue. I unplugged the IACV and the damn thing runs great but idles high like it’s supposed to. Pulled the IACV and it’s got some sort of white gunk inside the spring/plunger. I am assuming that it is not supposed to be like that. Anyone have any idea what that could be?
