My 93 3800 starts out with almost no power and hesitates for the first 1/2 mile no matter if its 10 F or 50 F outside...then it runs fine after that. Suggestions needed.....

When was the last time you had the fuel filter changed?

Have you checked the fuel pressure in your system?

Thanks for the reply
I changed the fuel filter last night. It fixed 85% of the problem. Now it just does it a little when the car has been parked for a while.
I dont have a way to check the fuel pressure.
Suggestions needed to completely fix it.......

Check your spark plugs. They might need to be changed because you were driving lean. How old are your plug wires?

also check all your vacuum lines. clean maf/ tb reset the computer it could be just confused now as it was so lean from filter.

That is true, the trim tables will take several starts and drives to balance out.

Thanks for the replies. The Plugs and wires have at least 40,000 on them as that is how long I have owned it but who knows. Ill change them.
Can someone give me a link to "how to reset the computer and check the codes" or tell me what section its in. I know I have seen them here somewhere.......

The tables will set them self over time. Or you can disconnect the battery for 20 mins or so and that should do it.
