Okay drive truck this morning seems like a slight miss what do I do I just put the injectors in??

If ya wanna fix it.... yes... it's gotta come out....
Once you've determined it's not some sort of connection problem.

It's weird it's kind of intermittent. Left work and it was fine..?

That's how mine is. Sounds like a connection. I haven't really cared enough to run it down. Clears itself up as fast as it starts.

P0266 is a problem with the coils on the injector, could be a connection or wire problem but most time it need a new injector.

Just installed the injectors last week.

Also is it normal for the truck to buck when you tap the throttle in drive or reverse? Just lopes for a quick second then idle evens out. Again contribution test came out good buzz test passed

That could be cleared up with your tune. I run the same injectors. Would stay just a tad bit high idle it seemed..... I would tell your tuner what it's doing.
Did you get the upgraded solenoids? ??

I'm not sure if I got upgraded solenoids I bought them from holderdown performance but they are warren injectors. Do you know anything about a ticking noise from injectors? Like I said before just put them in

Hmmmm.... can really hear injectors when it's running. You can hear valve train though.
You didn't hear any one loud injector when you buzzed them???

Yeah it just sound like a loud injector. Any bad compression or bad lifter would so up in contribution test wouldn't it?
