My truck has 230k but still runs great. However for the past few months, when cold (only 65deg overnight here), I try to drive away in the morning and when i touch the gas peddle, it stumbles down to like 100rpm and then has to recover, I really have to touch the gas lightly to get it to wind up (too much throttle causes the stall) then spin the clutch to get it moving for the first few minutes. I just put in a new cat yesterday, air filter is good, plugs, cap, rotor good. It helped dumping carb cleaner into it last time it did that, but only for a little bit, and I just did it a couple months ago. Any suggestions?

Fuel filter?

that was changed about a year and a half ago, i'm sure its ok because it runs fine once it warms up.

Let it warm up for about 5 minutes. My old Chevy did the same thing on cold mornings (just got to let the blood start circulating and then it is good to go).

There might be a problem with it, I never could figure it out, I just let it warm up and never had a problem past that.

Cold start injector?
