ACT
ok my car idles high when its warm at about 1200-1300 rpm when its cold it idles at about 900. its not an intake leak cuz ive sprayed the intake w/ carb cleaner several times and notihng happened. could my ACT or coolant temp sensor be bad? or do you guys have any other opinions?
also would a bad ACT or coolant temp sensor hurt my gas mileage? i used to get 20mpg and now i get 15/16mpg thanx everyone

RE: ACT
Ask the brain making the decisions for A/F and spark advance, check the system for ACT or ECT failure codes. If the system sees they are within specifications, why fix/replace something that is not broken........ DIY KOEO/KOER/Cylinder Balance Self-Test
