F-150 Start/Idle Problem
When starting my 97 F-150 (4.6L), it always fires up, but intermittently, it dies immediately. The only solution is to keep foot on gas pedal (@ ~ 1500 RPM) until the car gets to normal operating temp. Even then, it idles rough. Sometimes this happens, and sometimes not.
I've already:
1. Replaced plugs
2. Replaced plug wires
3. Replaced fuel filter
Any suggestions?

F-150 Start/Idle Problem
If you dont want to spend the money to get a drivability diag from the dealer you can keep throwing parts at it, but you could have a bad idle speed controller, bad vacuum leak, bad coil pack, etc etc. As you are finding out, sometimes its cheaper to take to the professionals and get it fixed the first time through.

F-150 Start/Idle Problem
IAC was my next item.
To be honest, the plugs, wires and filter all needed to be done anyway. It's my sons truck and because he's low man on the totem pole, my Excursion and my wifes Millenia get dibs on the garages. So he's stuck out in the driveway.
I'll go for the IAC in the a.m. and see how it goes from there.
Thanks for the help!

F-150 Start/Idle Problem
I have had the same problem with my '99. The problem has existed since about 2 weeks after I got my truck. Dealerships have thrown in about 5 IAC's and that still hasn't fixed it. Now it is 03 and about 122,000 miles on the truck and that is the only problem I have had out of it! Dealers just tell me that they can't find anything wrong so don't worry about it just let it do it.
