Surging Idle
 

I had this problem once before, but once my motor was rebuilt, it went away. Anyhow, this is what happened. Everything was fine, until I had to replace the lower rad hose. After doing this, the engine idle surges between 900-1600 approx after it warms up. On a cold start though, it seems fine. I tried bleeding it, I ran the car with the rad cap open. Any suggestions? Thanks. Oh yeah, I did a search, and I am sure there are no vaccuum leaks since everything was normal before I had to replace the hose.

When you re-bled, did you make sure to set the heater controls to full hot, but not turn the fan on?

How long did you wait with the radiator cap off?

Open up the back of you FITV and tighten it down...
