misfire? boost leak? vacuum leak? arrgghh NOW WITH VIDS! Options

ok so today was the first road trip to be taken in my car, but i made it like 20 miles and it started feeling like it was misfiring.

the other day i spoke to art about this problem, he said it was probably the same boost leak that causes my car to stall out when i shift to nuetral after my blow off valve goes off.

well i found this hose that was loose and replaced it and the problem went away (i said it felt like the car was missing, but i wasnt sure and he said boost leak) then i took off the hose and the car acted the same, little stumbly, and at idle it does a little "pop pop pop pop pop pop" thing.

today that problem came back 20 miles into my trip, but worse, i could definitly diagnose this as a misfire, the car was very hesistant when the gas was pressed and even trying to maintain 65mph i got some misfire-esque symptoms.

im gonna look in the bgb on how to test the continuity of my plug wires because i really dont wanna replace them if its not necessary, money is really tight ATM.

i just replaced the plugs with ngkr7e's gapped at .028 or .28 im not sure which, i used one of those round spark plug gapper thigns to do this.

yesterday i ran the boost leak tester idea that art had and found one, my throttle body was leaking, but that didnt fix any problems, i could not find any more but it had been a long day and since i couldnt hear loud hissing anymore i gave up, im gonna do it again soon with the soapy water bit.

does anyone have any ideas as to what my problem is? can a vacuum leak cause me to misfire?

could bad plug wires cause me to misfire only sometimes, not 100% of the time?

guys im pretty sure i am running ultra rich and hopefully i can figure out why soon.

so far i know that my ignition components are less than 1000 miles old, and my spark plugs are like 100 miles old, they are one step colder and i am only running wastegate pressure at the moment (could this be harmful?)

im going to test for boost leaks tomorrow, and i will be determined to make sure that i have none, and i hope this will fix my problem but something tells me it wont..

i am paranoid now thinking maybe i hooked something up wrong, or something major is about to go wrong, and its freaking me out, if you ask art youll know that i am paranoid about my swap and i ask him 1000 questions a day.

i got 22mpg on my last tank of gas, this was with not going over 4k rpms and also only boosting 7psi, if that will tell you if im running rich or not..

like i said earlier i took off my o2 sensor and the sensor, bolts, and o2 bung were completely covered in black, and right now since i am running no exhaust the exit of my downpipe is also caked in it.

this all means im running rich but what i want to know is if this is beyond the stock rich conditions, and what might be causing this.
