rough idle when hot

Update:

I took the fuel filters off and blew down the fuel lines. I also cut the filters open to see how much gunk had accumulated. Much to my surprise I found the inside of the filters to be perfectly clean! I guess my tank isn't as dirty as I had thought.

I switched out the rad cap, added foam strips to the spaces around the fan shroud, wrapped the metal fuel lines with rubber fuel hose and it looks like the problem is gone. It was 75F yesterday, I idled the car for 10 minutes with the AC on and blowing 40F at the vent and the engine temperature gauge stayed near the middle where it does during normal driving.

I'm not sure exactly which of the small things I did to fixed the problem but with summer coming I'm just glad that the car is handling heat better than it did. Hopefully it will do as well at 95F as it does at 75F.:paranoid:

Thanks for all the help and suggestions along the way.:classic:
