I have a 92 Ramcharger Canyon Sport plow truck that has a 5.9 fuelie that won't idle high when cold. If I keep me foot in it for a couple of minutes it will stay running, but if I start in and let of the gas it will die. What controls the idle at cold start?

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
