Ok where do I start, my car is idling really bad; I had a severly crack radiator that leaked antifreeze all over my engine and surrounding parts. I had the radiator replaced and I also had my spark plugs, hoses, and clamps replaced also. I also had my head gasket and motor mounts checked and that's not the problem either. I want to say that some antifreeze got in my fuel filter or some other part. I can cut the car on and gas it then it might idle and sometimes cut off; other times I can gas it and then brake and that's when my car starts to shake a little then sometimes cut off or act like it wants to. I have a factory 4 cyl VTEC. I need you guys help....I'm thinking I should get a rotary air control vac done on it......WHAT DO YOU THINK?????
