Theres a valve on the intake manofold, not sure where on a Loyall, but, it's black, normally sits on top of the t-stat housing, and has a wire going into it. Thoes get stick, and effect the fuel mixture greatly at idle when the car is cold or warm. It's called the AAC valve. on the ea81t's and ea82's fuel injected models. All fuel injected cars to my knowlege have them. My dad has a ford crown vic that has one of them and it went bad, made it so it wouldn't idle when cold as well.
