i can hear a hiss coming from the brake booster area tried carb cleaner and no rise in rpm if i block the hose and moniter my fuel trims should i see a change if that is where the leak is coming from?

The hiss its a vacuum leak. Try pushing in on the vacuum line running to the brake booster

Whenever your fuel trims are reading 16.4, that's a vacuum leak.
Find it and fix it.
Also, 97-98 TB/MAF have to be year specific.
So you'll be needing a 99-03 TB/MAF.

UPDATE- replaced lim gaskets, installed zzp coupler, ported and polished intake and blower, tested maf( good reading), replaced pcv, cleaned all grounds and battery terminals, ran cam2 for a couple weeks, and plugged acc vacuum port. my question now is can the map sensor be bad cause that is were the hiss is coming from?
