I just noticed that your coolant temp is low. Was that engine warmed up fully?. If so shoot an IR temp gun around the thermostat housing and record the highest temp reading.

Also, see if your TPS values keep moving properly when you get to rev limiting and press the accelerator pedal further.

Misting the whole ignition system and inspecting the ignition wires:

how do you add a video, I want to show you whats going on

 

 

 

I will be glad to help you but you have to answer my previous questions so we can narrow this down. Some possibilities are:

Fuel pressure
Exhaust restriction
Compression
Ignition
MAF sensor
TPS sensor
Airflow restriction
Timing

If you want to avoid the parts cannon, we need to narrow this down.

Here are the fuel trims.
mist test was good
strong spark
don't know how to look at the misfire counter
new AC delco cap, no carbon
what is CMP retard? do you cam position?

 

Your idle fuel trims are good. They are positive meaning that the O2 sensors are requiring the ECM to command the injectors slightly more rich to maintain minimum emissions. Then when you try to rev the engine up bank 1 goes to a significant lean injector command but bank 2 does not. What this suggests is that the problem is not global (MAF, coil, ICM, fuel pump, etc) but rather is specific to bank 1 which is on the drivers side. It also suggests that you are not starving for fuel. So now what?:

It looks like your using an Android app. I can't see which one but it should be capable of misfire counting and CMP retard . Get all 6 misfire dials up and see what happens when it boggs down. I'm guessing that there will be trouble on bank 1 cylinders. CMP retard measures the distr pickup timing which needs to be +/- 2.

It could be the fuel injectors on bank 1 cylinders but I don't think that they would be OK at idle and then leak and go rich. What is very specific to a given bank is the upstream O2 sensor. I believe that your software can graph the O2 sensor output. Capture that graph at idle and then full throttle. We need to see the voltage levels and the frequency of the square wave. A crude but effective test here would be swap upstream O2 sensors and see if the problem follows. Also does your TPS go from 0 to 100% smoothly through the gas pedal range (engine off)? I see that you are at 50% when it boggs down but what happens when you floor it?

Have you done a compression and leakdown test?

Your getting closer.

Thanks
waiting for it to cool down a bit then going to do a leak down test, I'm kind of leaning towards fuel pressure regulator, but I need to do the leak down to see that too.

 

I thought negative trim values were bad
