Hesitation until warmup?

[metalhed]

Since the weather has been cooling off, I've noticed that if I don't let my truck warm up to operating temperature it'll stall and surge once I put it into gear and give it some gas. It only does this in the morning after it's been sitting overnight.

I checked my MAS and it looks clean, so I don't know what it could be.

It did this last fall/winter too, so I was hoping to find a solution. It won't happen at all in the summer, I can just start it and drive.

Thanks for the help.

Yep, give that a good cleaning and you'll be all fixed up, just did mine about a month ago and it helped a TON.
