First 2 are from cylinders 1 and 3 ( the ones that were "misfiring")

I'm starting to think my fuel injectors are clogged, it hard starts when cold, I had a misfiring problem, and I feel hesitation when I gas it. Any second opinions on that theory?

plausible, since you already did the filter I would say next shot is injectors. They are easy to pop off and clean.

Plugs look pretty damn good to me. Were they wet when you took them out?

Plugs were not wet but the car hasn't run in 12 hours, the coils and plugs were tight. How exactly do I clean injectors? I want to take them out and do them not use techron. What's the most effective and easiest way for a regular dude to clean them correctly?

Gapped the plugs to .028 inches, they were all between .034 and .038. Started up but I still think I may have a fuel injector problem, anybody know the est way to clean them without and other those rigs people uses with the switches?

That might not be the only issue, but it definitely wasn't helping. You should feel much better response from the engine.

As for cleaning the injectors, do a search for seafoam treatment. Good stuff. I use the following method with good results:

One full can in a full gas tank. Half can in the crank (where you add the oil to the engine) and a half can through the vacuum line on the intake manifold. Change your oil when it's time to refill the gas (about 300 miles).

I just did the seafoam treatment about 200 miles ago. I think either the injectors are too clogged for that to do much or my injectors arnt the problem. I ran it through the crankcase, the tank, and the intake. One thing I know for sure is that the engine is not getting enough fuel, I can feel and hear it.

Wow didn't know the bkr7e went all the way to .038 without being compensated. Definately needs to be around .028 (or less). I had mine all the way down to .022 to stop misfires before I decided to upgrade to 2.0 ignition.

Have you thought about doing the fuel filter, its cheap and easy.
