i think it's a vacuum leak to your manifold, maybe one of the intake manifold gaskets, maybe you should try just tightening the bolts to the manifold & plenium, um check all your hoses for cracks, any holes, and just push them onto the nipples as good as you can. Then I would check a vacuum hose diagram on your car just to make sure all your vacuum hoses are ran to the destinations they are supposed to be ran to. The only other thing I can think of would be to check your belts, make sure they are tight, but not too tight; on the pulleys. I have had a few different things cause a pulsating senstation while accelerating in my 94' prelude heres a couple that I have had.
1). Clutch starting to go (slipping of power type feeling)
2). Fuel injector leak (smell gas, not very much power, lots of vibration while accelerating)
3). Vacuum leak from vacuum hose leading from plenium to cruise control actuator (large power loss, idle was constantly changing, vacuum gauge wouldn't stay constant in hg. while accelerating it felt jerky or vibrant throughout the rpm's I traveled)
4). Loose power steering belt/ alternator belt (loss of high end power, fluctuating idle, fan came on often, ricey farty sound when flooring the gas, acceleration wasnt overwhelmingly awful but not steady throughout rpms.

start there, if those don't help keep posting, timing belt if it is missing a couple teeth or is old can start to skip and you will feel like your car has a huge miss in it, but as far as bleeding the clutch if anything your pedal should feel pretty stiff if it doesn't need to be bled, where as it should feel really soft if it does need to be bled, you could need a transmission flush or gear oil change, this is going to sound dumb to a lot of people but if your power steering reservoir is close to empty or is empty your car will run like shit and sound like it too. It could also be a clogged catalytic converter but if it is the only way to fix it is get a new one, if it is a clogged catalytic converter it will feel like you have absolutely close to no power. you could also try cleaning out your fuel filter, intake manifolds, air filter, fuel rail, injector spray tips, anything that carries fuel or air you can try to clean. let me know what you come up with goodluck!!
