running rough

Replaced injector and pedestal o-rings and now truck is running rough, runs like it has a soft miss. no check engine light.
Any ideas?

Needs to be driven hard to purge the air out of the system.

Sorry guys, I didn't do injector O-rings, I did pedestal and turbo o-rings. I don't know why I said injector. anyway the truck is running rough at idle, down on power and sounds like it has a soft miss. with no check engine light. truck is completely stock other than exhaust. stock pedestal, turbo the whole 9. I am looking at injector harness now and doing the 25 cent mod. any other ideas? IPR maybe?

does it only do this at idle and also how much fuel is in your tank if its less than 1/4 you might have the problem I had and the black foot broke off the lift pump in the tank.

Check to make sure the baby's but is in place correctly on the back of the turbo. If the pin isn't in the hole, it will cause an exhaust leak that leaves you low on poer.
