Not yet Null Head haven't had much time but you will be the first one I let know i I almost got it narrowed down to a vacuum leak I mean it's a good work horse last week I hauled two loads of shingles to the dump it just dies alot especialy when I come to a complete stop then when do get started again and her some gas she'll supter and hesitate then take off and the some times I get back firing around the throttle body I don't know buddy we'll geter figured out

 

I want to thank everyone again who tried to help me especially my good friend NULLHEAD, well buddy just to make along story short I found my vacuum leak and actually it was a cheap fix I put a new TBI gasket along (I all ready put the TBI gasket on a month ago but the big fix was the Permatex 2 )with permatex gasket maker 2 on the top and bottom well TBI came from the junk yard and it had the protective cover missing the for idle hex screw so the idle was set to fast but once I figured it was hex and not Philips head I adjusted out now she purrs like a kitten . Thanks to all my friends at truck form.....Bassconquer

 

I am having the same problem too, BUT . . .
My truck is a 91 C2500 with a 93 crate motor that's got less than 6000 miles on it.
Sometimes, not all the time, but sometimes it stalls out when shifted into gear, or when the AC compressor cycles. Otherwise the truck runs great.
Sorry, I don't want to hi-jack the OP's thread.
