Dealer said they couldn't fine anything wrong with with my truck( no surprise)
Whenever I push in the clutch no matter how fast I'm going the truck will die, dealer says Lift Pump pressure is fine and Injector Pump is fine, pressures are good. And no codes.

Any Help Would be GREATLY appreciated

 

Probably too low idle speed.
Any mods such as governor spring kit or washer?

 

Really helps us to help you with a signature or a description of your truck. If you're in a winter zone, a location is nice, too.

 

my truck does the same thing if i shut the key all the way off and restart it then it will work fine i think its a prob with the shuttoff silenoid
