Explorer idling problems
I'm having a problem with my explorer. It seems as though when I start the truck up, it idles weird until the temp goes up. The RPM will flutter, from 500 to about 800, with barely a second in between each pulse. The entire truck will shudder until I begin driving, then after a few miles (or it warms up to about 1/3 of where the heat gauge is supposed to be), everything is fine. Horsepower lagging as well, it just doesn't seem to have the same power as before. Suggestions?
I already cleaned the carbon out of my IAC valve, checked it recently, and it's pretty clean still. I'm thinking air filter or something to do with the air intake.

Sounds like classic intake manifold o-ring problem. I had mine done over the summer and what a difference between this winter and last. The other symptoms of this are that the problem gets worse the colder it is and that it goes away when the engine starts to get warm. One thing you can get your mechanic to do is to spray your intake area with carb cleaner when it's cold to see if the problem stops for a minute then picks up again. Good luck.

Hi, I should have mentioned that the idle rpms is when the truck is in drive with the brakes one. As for your other questions I am sorry but I can't help you there. Maybe a service manual (haynes) would be of help. Maybe someone else would be able to help you out. Good luck.
