weird problems

I just bought the truck but like it has a few issues that worry me though. Runs like **** when cold smokes like hell glow plugs i hope. Also when at high rpms the truck makes a weird rattling hissing sounds. I thing the clutch is slipping and when i let the cluch out the truck jumps. And the only code is a p0491 or something for exhaust pressure sensor. The trucks runs good when warm gets almost 20 mpg. One more thing when i go to shut the truck off it sounds very clacky like a rod or something i hope its not the problem but im not sure any helpful advice would be great
