DYING SPORT TRAC 3

I've changed the IAC valve, replaced the vaccuum hose elbow and my truck still sometimes tries to die when I shift into neutral or park. Any more suggestions?

Dealer claimed I had an intake manifold gasket leak, I think there's a TSB.

mine did this too.. dealer changed the IAC, but it didn't fix it.. so i started investigating and found the butterfly valve in the intake was very dirty.. i cleaned the valve with carb cleaner and a rag and the problem went away..



good luck

Those last two posts are a good idea. I'd try that first before going forward.
