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.

So, new MAF installed and started right up and still running with a cylinder 1 misfire as well as weird idle that slightly jumps up and down. I'm sure the ECM and everything needs to learn and adjust what's going on with miles. I'm trying to make them easy mile and slowly, no trips down to the beach on the interstate I feel that would / could hurt it. In the video is a small clip of the idle doing the same thing as before.

So I went over the engine bays vacuum lines and found 3 small lines that were dry-rotting and breaking down and starting crumble in my hand and replaced. I also used most of a can spraying all gaskets that I could get to without any successful change in idle.

I remember back a while ago there wad a intermittent issue sometimes when I would press the gas pedal after backing out of a parking spot or to take off from a stop and there would be no response until I shifted to neutral and gave it a couple revs. Could this be a sign of the crank angle sensor?

I'm not sure if that's what it's doing, until I can afford a scanner that tracks data instead of just a code reader, I feel I'm SOL. Is it possible that the plugs the mobile guy put in just aren't happy in this motor? It seems far fetched durle yonit still running.

Limp mode sounds actually perfectly accurate. Now for TB cleaning can I unhook the MAF to take the intake apart while battery is still connected without starting the engine or any sensor for that matter? As far as opening the butterfly would I be able to put the ignition to the on position? (Push button on twice no brake pedal) and put the car in drive and would the TB actuator open for me to clean it?
I still can't seem to figure out the tick/tapping coming from under the vehicle that only makes noise when the engine is under a load. It won't do it while idling or revving in park it also won't throw the flashing CEL unless moving as well. Thank you and I hope these make sense.

Okay, so the MAF can be unplugged in order to remove intake tube and box, but the throttle body harness cannot?
The plugs removed were
Denso p/n- FXE22HR11
what the guy put in were
NGK p/n- LKAR7BIX-11S
I know iridium tipped are pre gapped and I don't have my feeler gauges to even remotely check but are the replacements even in the correct heat range is a question? I'm buying a scanner tool hopefully tomorrow to gather more data. Fuel trims ect.

I was able to get the tb to open using the car with ignition on and in gear and throttle pinned down with a jack handle and snap a picture. Is that all the wider it opens? It also looks pretty bad in there.
