As I told you, you need to take off your entire piping system and squeeze each hose and inspect.

Ah ok, I was wondering if I was missing something, because that would have been where I would have started. Good to know somebody is looking out.
this is probably a loaded question but f-it i need something to read during o-chem. do boost leaks really cause that many problems besides the loss of power? more to the point what is the engine thinking or doing under boost leak conditions

You try and accomplish a lot, and the community is grateful for it.:icon_bigg
I'm just glad you mentioned it to him because I though I was going crazy.

A boost leak allows metered air out of the intake. Air the ECU thinks is there, and continues applying fuel for, this causes a overly rich condition. Overly rich conditions can cause many things, including stumbling, cause by soaking the spark plug, which can foul the plug, shortening its life. The loss of power encured by stumbling if it is bad enough can place uneven loads on the engine causing premature wear. If it is rich enough it can load up the intake manifold raising the possibility of a backfire, causing possible damage to the throttle plate, gaskets, and valves, as well as a remote but possible damage to components on the vacuum lines running from the manifold. Also if the A/F mixture is to rich the unburned fuel could travel into the exhaust manifold completing its combustion there, this is hard on turbo chargers. Also if the boost leak is big enough with our cars it can cause you to run into fuel cut very early. And the more boost you run the more the situation can compound it's self with any given leak. Of course these are all just possibility that can result from a boost leak. A rich condition is almost sure to occur unless your are already running ridiculously lean and the leak is small.
CAR IS FIXED!!! toyota mechanics couldnt handle it!! lol.. well i was talking about how i put that new intake stuff on right before it had the problems... so i took that off and put the old filter on.. car drives fine now... ok so heres the wierd thing.. the way it is now and the way it was before was with just an air filter going around the 4 bolts on the afm.. no adaptor..lol. so theres a small gap between the afm and filter.. the car drive great with it like that.. when i put the new intake system on it was tataly closed up.. and the car drove like crap.. why is this?? the only thing is the car still idles bad...any suggestions??
what do you mean put a bandaid on it?? its fixed.. the intake i had on it was way to restrictive or somthing like that so it wanst geting enough air during boost.

Thats not what I said at all.
I stated that you switching from an air filter that sealed propperly (making the car run poor) to switching to your current air filter that doesn't actually seal up against the afm, led me to believe that you have a crack, hole, or some other opening after the afm.
This would make sense: sealing up the filter causing more of a vacuum post AFM causing a pirate air problem.
