The other day I noticed that when I attempt to accelerate quickly while in 4th or 5th gear the rpm's will wind up but the car doesn't go any faster until I back out of it.....Is there a clutch adjustment or am I screwed?

Thanks!

Clutch is slipping... get ready for a new one. Might as well upgrade it while you are at it. Check out http://www.specclutch.com/

Looks like your clutch is slipping. Prolly the best way to make sure is:
put it into 5th gear while going 30-35mph and press on gas, if nothing happens, then your clutch is still maybe OK, if it slips-then your clutch on its way out.

That's how I first noticed it. 5th gear, step on gas, rpm's go up and speed stays the same. WHat's a clutch job going to cost me?

You have to buy a new clutch, good time to upgrade so go with a southbend www.kineticmotorsport.com A stage 2 is a good direct replacement and will last a lot longer because its a kevlar disc. Just make sure to break it in nicely for a few hundred miles.
Clutch labor can range anywhere from $700-$1,000

Thanks for the info....It really pisses me off to loose a clutch at 70k though.
