no idel on a cold start 5.4

[EArmsF350]

just bought another run around truck for the farm. 2001 f250 4x4 with the triton 5.4. 196k and immaculate condiition. Its cold here in Kansas and since I bought it, it will not stay running after starting it cold. I hsve to keep feathering the throttle until it decides to run by itself or I give up untill I'm ready to get down the road. I put in NAPA's higher quality Throttle Position Sensor. It helped for a few days but went right back to not wanting to idle on a cold start. What else could it be? Mass Airflow Sensor? I was told to replace the fuel filter, that wouldnt help my problem would it?

A fuel filter may help. With almost 200k, there is probably a good amount of sediment built up in the gas tank. If the gas level gets low and the pump sends enough of that junk towards the filters, it could easily clog it. Give it a shot.

why would it not idle when cold? It runs awesome when its warm and it starts and runs great after warmed up..... Im going to take it to the shop. Thought I would try here first for suggestions. Thought maybe it is a comman problem.....

It's common for a clogged filter to give those symptoms when cold and then disappear when the truck is warmed up to operating temp and/or at higher speeds. Let us know what happens when you change the filter.
