Surging and hard to start somethings. When the engine is cold I have to give it a little gas "only sometimes" and then it starts with a puff of smoke. Smells like raw fuel. Seems to be loading up? 110k on engine just did a major tune up. Plugs, wires, fuel filter, all fluids, and injector cleaning at Ford dealer. The problem was there before tune up. I tried to do a search but didn't know what some of the parts were just looking for some current and sound advice.
Thanks,Dan

 

It sounds like you need to pull your codes. It sounds like maybe your IAC (idle air control valve) is dirty and sticking.

 

Where is the IAC? I guess a local auto parts store could check the codes. Its warming up know I can work on vehicles just not sure of the newer ones. I had the dealer do my tune up because of the weather don't think I'll let them do that again. I ask them to check everything because of the miles on the truck. Thought they would be more willing to go the extra mile knowing they would of had a little more income.

 

It is bolted to your intake manifold with two bolts. It has a wire going to it with a small motor looking thing on it. The manual says it can not be cleaned but I don't beleive that, they say replace it.

 

Thank you, I will start with that. I'll let you know the outcome. Dan

 

I had a problem with starting also. Idleing was an issue. So here is my experience.

- If you buy a new Idle air control valve, the part is called a motor. I had trouble the first time a parts store tried to find it for me. I forgot the exact name that ford uses but it helps to know it.

- They vary in price a lot depending on where you go. Ford wants over 100.00 for it and I found one for 43.00 at NAPA.

- I cleaned mine the first time at 56,000 miles and all was well. I just shot a little SuperClean in the hole and rinsed it out with water. Blew it out with compressed air and re-installed. Engine ran fine. (Make sure when you re-install it that you install the little piece of hose that brings it back into the Air intake system or the truck most likely will not run. Mine did not)

- I did finely change mine at 140,000 miles because I have a miss in my truck at the moment that I cannot find. Cleaning mine got me another 60,000 miles or so.

Anyway that is my story.
