Seems like I go through this every year. My SVT is idling at 1200-1800 most of the time. Once in a while it will drop to the normal 750, but it will usually hang at 1200ish before doing that. Over the past year I have changed the following:
IAC
TPS (More than once)
MAF
UIM/LIM Gaskets
EGR Gasket
IAC Gasket
I also have the TH fix in place. Does anyone have any ideas how to fix this? I am not seeing any CEL codes at the moment, but the last one I saw was a P1120, so I replaced the TPS again.
TIA,
Mark
