Question about 1999 Ford F150 Regular Cab
My truck stutters while idling and seems like it wants to turn off. in fact it has turned off a few times, but not while i have been on the road. i have changed the plugs, wires and the fuel filter and the problem still exists (improved somewhat). when the truck is on and in "park" the rpms are at 900 when i shift to "drive" it goes down to 600-650 rpm and that is when the truck stutters and shakes, like it wants to turn off. what is going on with my truck? any help and advice will be greatly appreciated. please respond to my email if possible: email@example.com thanks.
Try cleaning the idle control Valve( IAC). Buy some brake cleaner and remove the duct work from the air cleaner system. start the truck and have somebody run it to about 100RPM and spray the cleaner directly at the valve. It is just inside the air cleaner.
