Unplugged my battery for a bit then plugged it back up to restart my ecu and now its throwing 55 which is fine. For some reason every time i try to take a video of it it decides to go just fine. My timing is good because it was off by a bit previously and had my brothers friend set it right so that should be fine. ive taken my iacv off and cleaned it not too long ago maybe a month so it should still be clean. Havent had time to play with the iacv and adjust it where it needs be since its kinda hard to reach with my intake mani.

Try taking off your iacv and cleaning it with some carb cleaner. Spraying it down the tube isnt very effective really. just google how to take it off it should be pretty easy, think 4 bolts. and clean it thoroughly spraying it alot and making sure the spring is clean. when your throttle plate closes its up to the iacv to provide air to the engine at idle. sometimes when its dirty it takes awhile to open up and let the air in hence the car dipping down then coming back up after a couple seconds.
As for the whining, my ka ps pump used to whine alot but mostly when i turned the wheel. i just added more fluid in it until it didnt whine anymore and couldnt fill it anymore and i was good.
