So I finally got my car running decent, but I have a high idle that comes and goes. When I first start it cold, its up at like 3000, then after it warms it goes down to like 1200. But if I start it again, when its warm, it goes up to 3000 again and then comes back down after a minute or so. And after I took it for its 2nd test drive I was pulling into my garage and it was back up to like 3000 and then when back down. Any ideas guys?

 

bump for info.

could my wriing to the ecu be causing this in any way shape or form?

 

no one knows? come on honda-tech.

 

never mind guys I fixed it.

Seach function

For future reference it was that valve under the TB with the two coolant lines running to it. ftiv valve or whatever the **** it is. just take it apart and screw it back in and no more high idle.
