OK I have a bad problem about truck smoking like crazy at idle it's fuel smoke. I've checked timing, checked compression, changed injectors, rechecked cam timing, checked valves. Checked for boost leaks, pretty much anything you can check except injection pump. Motor is a dry block. When I say smoking bad it's loading motor up enough that's it's missing while idling. I've pulled fuel out so much that it almost cleans loaded smoke up tonothing but still on help at idle. It started doing so between loading truck up one afternoon it wasn't running like that to lining up to pull that night and it had started it. Crazy thing is once you get truck up around 3k it will clean out and run pretty good down thetrack but it's falling off rpm pretty hard out of the whole that it wasn't doing before this problem started . Any ideas what I'm missing? It's a new schied ag pump with probably 12 hooks on it.

Have you checked your injectors? Could have one or more cracked.

On edit I see you changed them.
 
What fuel are you using? Did you put fuel in the truck after you loaded it but before you ran? Does the fuel have ethinol in it?

All i run is red off road fuel. I have a 4 gal Tank and have toped it off at least five times since this started. This problem started around 3 months ago, 8-9 hooks ago. As far as ethinol being in it i'm not really sure i'll have to look next time i get fuel, i get fuel from same pump in town most of the time.
 
A guy I pull with has the same problem. His never did it till he sent the pump off to Scheids to be rebuilt. I don't know what would cause it though.
