ok 1st of all i searched and advanced search and no similar topics. so with that said, i replaced my thermostat and to remind all, i have no cel nothing wrong to my knowledge and after replacing th thermo the idle surges. why would changing a thermo cause this? i understand it could mean iacv or ect but all the sudden after replacing thermo makes no sense unless their is air in the line right?

 

ok never mind iacv ! cleaning it now
