Oh ya I know..went thru 2 bottles of spray..no luck..replaced many lines incliding one under sc...heat control one..map sensor..pcv valve..checked and sprayed egr pipe..not sure where it is..either ssic is warped..I spray all around it no change in idle..or maybe the sd headers leaking..they are wrapped in header wrap so not sure...just thought it was weired when u take cap off trims run better...and evap line is good and even zip tied
