Looks like fuel is not going into cyl. Those look clean. Does ur fuel pump feel like it cuts out?

It feels like a misfire, but it only happens in drive. The miss may be from the fuel pump cutting out tho. The car jerks when I'm driving and acts like it's going to die. The car only has 57k miles on it.
You could try running some Chevron injector cleaner concentrate through it. You changed the injectors already though.

He could swap injectors around. 3 into 4 and 2 into 1.
If the misfire comes back into cyl 1&3 again then injectors are fine.

I like that idea.
How are the plug gaps?

Running the NGK iridium plugs. I didnt gap them, but I did carefully check them with a feeler gauge and they were right on. I've swapped them around a few times checking stuff and its still cyl 1-3 missing.

And the injector swap idea wouldn't help. I've put new injectors in and it still misses on the same 2 cyl.

Pull the valve cover. Check the rockers on cyl 1 and 3. As well as the cams

I'm gonna have to do that either over the weekend or next Tuesday. I get off at 10 every night so its tough.
Well you've ruled out the combustion chamber, the valve actuation system might be off. This is odd.

I'm gonna check timing and rockers on Tuesday since that's my only day off.
