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?

well i replaced the wires today and it still does it! ARGH (i also found out my old wires were oem and had less than 1000 miles on them)

82.75 down the drain

its idling at like 600 rpms.. and art suggested i try capping off the vac line that goes to BOV and it ran a little better, but still hesitated and backfired, just seemed to do the whole process faster if you understand.. i didnt wanna drive it too hard or long without a BOV so i parked it and came inside..

art suggested removin the bov completely and trying that, so i guess that is my next step..
