Cold Weather Trouble

Hey, I have a 1998 F-150, and its having trouble starting the past couple of cold days up here in New Hampshire. At first I thought that it was the starter, but the truck would go through spurts where it would turn over for a split second. So the starter problem is ruled out.
Another issue that came to mind in the cold air intake that I put on a couple months ago. Could the truck be getting too much air trying to start it in the morning? Could the air be too cold/thin for the motor to run? Once the temp. warmed up a little it started up. Oh, and also, when we start it in the cold, to keep it running we have to lay on the gas a little bit so the RPM's stay up, or else it boggs out.

Any advise is awsome and greatly appreciated.
Thanks you guys,

Garrett

So is it cranking? You say the starter will go once and a while? Sounds like you simply don't have enough juice to turn-er-over....maybe dead battery?

I know that the starter is on its way out, but that is not the problem in this scenario. I have come to the conclusion that it's getting too much air when it's starting, and not enough gas...the truck is trying to start too lean. cause when I start it i have to play with the gas pedal a little bit. my father and i were wondering if there is a sensor that should have been changed. Like a high idle sensor, or someting like that.

Thanks again guys,
Garrett

Idle Air Control Valve. If this is the problem it will turn over and then cut off. I have a picture of it in my gallery.
