Slow to go after it is started

[David '96 993]

I have noticed over the last couple of weeks that after I start my truck when it has been sitting over night or longer, that it hardly accelerates. After a couple of seconds (sometimes longer), it eventually gets going like it normally does. Note that it only does it when it has been sitting for a long time.

It feels like it is not getting fuel...but no clue what it really is.

I think mine does that sometimes too, i have a 99 f250, its like sometimes when i first start it, its a pig, and will barely move, but after a while it hauls butt

Matt,

Thanks for the suggestions. I will look into them.

For now, I need to let it warm up for about a minute or so before it will go.
