Unsteady RPM's
 

Alright iv been noticing my engine dropping off every now an then lately and now it's doin it everytime i get into the gas.

You can sit and watch the RPM's drop about .5 then kick right back up, i guess you could consider it hesitation, i already have an extreme amount of power loss due to a blown plenum and this is really starting to get on my nerves. The plugs/wires are new, i havent changed the cap an rotor in awhile so im sure it's due for a new one, i know it wouldnt be the transmission slipping under acceleration because if it was slipping the RPM's would rise not fall.

No i havent checked the fuel pressure, or compression in the cyl's. I dont have a CEL on and i know the CEL works. At this point im really pissed off and i dont feel like messing with it so im just going drive the damn thing untill i can mess with it. But if anyone has any suggestions other than the usual ideas then i'd be greatful.

hesitations that clear out after a few seconds might be a vacuum leak.

Any idea on which vacume line that might cause it ? i know i have wild vents so theres something going on in the vacume system. But i got no idea where to start

to test for a vacuum leak, temporarily cap off all the ports on both sides of the manifold and try it. if better, then it proves its a vac leak, so then add them back one line (or segment) at a time to find the culprit.

you're talking about the one's that plug into the keg right ?

Something as simple as a plugged PCV valve or hose? Weak ignition system? Throw a vac gauge on there and a compression test when you can. You seem to have all the right idea's.

yes. both sides.
brake booster, pcv, cruise, heat/ac, all those. cap them off temporarily.
