The bottle of injector cleaner seemed to help it run smoother but the idle problem is still there. My dad's girlfriend wanted to take the Civic into Honda because the SRS light was on and she didn't like that. While it was at Honda, we asked them to just LOOK at the idle problem. They said it was the Idle Air Control Valve (IACV) and they wanted $300 to fix it. Rip-offs... Does anyone know of any places where I can get a new IACV and where I can find instructions for replacing it? Thank you very much.
