Codes P0300 and P0301, Injector problems?

Did my message of cylinders 4 and 6 not load? Cylinder 4 is 150 PSI and cylinder 6 is 160 PSI. I am baffled at this point and waiting on the intake boot. I would like to clean or at least check the throttle body but I'm a bit apprehensive due to the drive by wire issue that could happen if the butterfly is moved. I have the re-learn instructions and I feel that if the battery is unhooked it should be okay, I think.

Exactly how I ran the comp test aside from warm. In order to get to bank one cylinders the plenum has to be removed. Fingers crossed the boot shows up tomorrow and I will clean the throttle body gently tomorrow. Here's today's code printout. Fault means it is not working at all, correct? Happy Halloween!

So I finally got the new boot put on and well nothing absolutely nothing has changed. I tried spraying carb cleaner around vacuum lines and what places I could reach with no change in idle. I have noticed when driving at a slow speed when just barley using the weight of my foot to accelerate the throttle still misses but then seems to 'clean up' and all of a sudden goes for a little but as soon as it shifts it starts again and the engine light flashes until I let off and stop (idle). Almost like a carburetor would do if timing was not quite right would. CPS comes to mind, but wouldn't that be a code as well? And where even is that on this motor? Timing side or back of the block? Is there a way to test it with a multimeter?

If memory serves me right that may have been one of the original codes along with the p0300, 301. Is there a test for the wiring with actual acceptable range on this car?

I ordered one online and should be here tomorrow.
