The truck listed above acts like it is running on two cylinders when cold. Runs fine when it's good and hot.

Hi,

When was the last tune-up? When it gets colder outside, the fuel mixture is much richer when it's first started. If you have old spark plugs, that can cause it.

Also, take a look through this link. It explains how to retrieve diagnostic trouble codes on this model-year vehicle without a scan tool. Try doing this to see if there are any diagnostic codes that may point us in the right direction.

Let me know.
