Alright well sometime either this morning or afternoon I will post a couple videos of it running cold start and when it warms up. Big difference. Just to let you all see what's going on. Appreciate all the ideas and all the help

 

Hot idle. Knock and miss

 

Cold idle. No knock. No miss

 

Never, once installed properly they should be good forever.
If they are not pounded down all the way by hand, THEN torque the bolt to 120 inch pounds, they can come loose.

Yes, but those injectors have good, fresh o-rings so I would suspect something else.

Bill, did you remove the chip and see if there was a difference?
I'm not saying that's your issue, but I would try some good tuning for your exact set-up before going any further. If that issue persists with tuning, then I would suspect an injector issue. Try to narrow down the injector, have the valve covers off and unplug them one at a time (when it's warm, when it's knocking) and listen for a change in the motor as you unplug each one. This works better than a scan tool. You can do this test now, but if you get a consistent drop across all 8 it's probably something else and not injectors.

FWIW My '96 has Stage-2's with what I consider very good tuning and I swear you could have videoed my truck, it acts just like that. Just the nature of bigger injectors without live tuning, IMO. I know my truck runs well and makes a racket when warm, and I know adjusting the tuning will resolve my issue.

Would also be helpful to monitor ICP and IRP duty cycle when cold and when warm (when it knocks) just to see.

If it was a loose injector from improper install it would do that knock all the time and develop lots of white smoke.

 

Yes I took it out and it didn't change anything. I will try the unplugging this weekend if I get the time. My IPR will be here and I will do that first and see what happens. Thanks for all the help. I'll let you know what happens when I get it do e
