rough after new injectors

I got new stage II injectors, and got them in this evening. It's idling really rough, and sounds like it's randomly dropping some cylinders. I drove it, and it was blowing a ton of white smoke when I got into it a little. Also, the throttle wouldn't hold the motor at any rpm very well. How long does it take to smooth out after you change them? Also, any ideas on the white smoke? It was doing that before the new sticks, and the dealer and they said most of them were bad, so I figured I'd go bigger instead of paying them to put in stockers. I appreciate any help yall can give me. I've been driving a dodge for the last two weeks, and I really want my truck back.

thanks

Check the UVC harness. It sounds to me like you have some bad connections or a bad UVC harness.

I would have an injector buzz test done as well as a cylinder contribution test done. This will help pin point the problem.

Another problem could be fuel supply or HPOP problem. Being I don't see anything done to the fuel supply system besides that FPR shim. You may very well not be suppling enough fuel to the new injectors. Bigger injectors need more fuel.

But I do not think that it is related to the tunes, how ever it is possible.

You have to drive the truck for several miles to bleed all of the air out of the high pressure oil galleries in the heads. The oil drains when you remove the injectors unless you use the drains on the heads beforehand. I know this is an old thread but it might help someone in the future.
