Still having problem with the idle and would welcome your suggestions...

I need to check the MAP sensor pipe but not convinced that's at fault because it idles fine when warmer, after about five minutes.

Works done so far...
  1. water temp sensor replaced
  2. valve clearance set
  3. ICV cleaned...twice!
  4. found the source of the hissing (not inlet related)
  5. system appears to be without leaks
  6. new air filter
  7. new NGK BPR7EIX iridium plugs


I'm wondering about wear in the ICV and the measurement of the little nut on the end

Could it be my C&B inlet cam is causing the problem, idle when warm is still lumpy but I can't recall what it was like before?

Might look at replacing the plug leads...any other ideas?
