I have a 93 Ford Ranger with a 4.0. It continually wants to idle at about 1100rpm. We have checked all the vacuum lines off the tree at the back of the intake manifold. New AIC valve, transmission vacuum modulator, fuel pump, fuel pressure regulator, new fuel filter, replaced vacuum line to fuel pressure regulator. No codes show up on the computer besides the 111 which is all clear. Have not adjusted the idle screw. This isn't really a problem driving normally but when you want to stop on snow or ice and the truck is still trying to push you forward it gets scarry. Anybody have any other ideas of what to look for?
