99 civic accel. problems...

hi,
as of yesterday, whenever i try to accelerate in 1st and 2nd gear in my 99 civic, the engine revs up a bit more than usual when i push on the gas, but it barely moves. once i get going and up to speed, it's ok, but still rev's a little high. is this a transmission problem? or something else altogether.
also, i know that one of the bearings in the transmission needs to be replaced(rattles a little in 1st and 2nd gear) and i also just got done having pepboys install a whole new distributor and plugs the day before.
any info at all is greatly appreciated!
thanks!

Sounds like the trans is slipping or the clutch is going if its a 5-speed

that happened to my friends 00 gs'r burnt out clutch, cost him 400 to fix

before u go ripping everything apart...i would just check to see if your cat melted or got plugged up.

i dont see how that would have anything to do with the cat... my guess would be the clutch
