June 6, 2006whats up guys looking for some help. '99 f-350 with a v-10. the thing does not idle very well, it kind of surges. It doesnt die out or anything, and as soon as I tap the gas pedal it smoothes out. I've heard there have been many problems with the idle air control valves, but that when they go bad or get dirty the vehicle wont idle at all. is it possible that the ide air valve is my problem and if so where can I find it on a v-10?

June 9, 2006On the top of the engine in the middle towards the back. Looks like a small solinoid attached to the back/top of the intake manifold. Has two bolts that hold it on....you can get one for about $50 at a parts store and isn't that hard to change.
My did the same thing, changed it and have had no probs since.
June 11, 2006O.K. I replaced the IACV and still have the same problem. any suggestions could the EGR valve be the problem?
June 12, 2006Did you reset the computer after you changed it?
June 13, 2006No, But I just tried that and no luck. Can you just take the negative battery cable off to reset it, or is there something else I need to do? I also found a hole in the hose coming from the PCV going to the intake manifold, I replaced it and I still get the surge @ idle I'm stumpped the only thing I can think of is the EGR valve. How frustrating!!!
June 13, 2006Yes, just take the negative off for about 30 minutes. Did you do what F1500 suggested:

When that happened to me, replacing the Idle Air Control Valve worked.
June 15, 2006This sounds like the same problem i am having right now, it only happens in gear especially in reverse, the rpm's surge up and down and it stops after i get up to speed, i cleaned the throttle body and the AIC and it is not as bad but still happening, i am thinking about the EGR now too????
Someone has to know how to fix this!
June 17, 2006That was going to be my suggestion, clean the throttle body. I've used carb cleaner and a toothbrush and make sure you get all the way around the inside and all around and behind the throttle plate. When I was a tech that took care of it maybe 90% of the time. Good luck finding it.
