    its very possible, take a multi meter to the battery see if its got about 12V. with the car on it should be around 14.1-14.4V.

    Re: weird noise

    wouldn't be the alt. its running fine. if it feels like its bogging down mashing the gas, possibly the cat converter is clogged / junk.

    but the noise is like spratic and when it does do the noise it runs bad and then it will run fine

    i dont think its the cat i a hole in the flex pipe so if the cat it blocked then it would just go out there

    Re: weird noise

    pull the powersteering belt off and see if it still happens; i've also seen ac compressors do this before seizing up all the way. GM 3100 and 3300's were notorious for this and they even sell a bypass pulley for them(GM; not 3gees).

    check your distributor and T-belt tensioner.

    It's hard to hear the noise in the video. Is a belt slipping? How old are your belts?

    Re: weird noise

    If your alternator bearing is going out, it could put out voltage just fine, but still make horrible noises. You can pull off all the belts and rotate things by hand to see if there is roughness or play. If it is intermittent though it could be hard to tell.

    it could, and did on my buddys cutlass at first, then it made the noise all the time and evetually seized up. i don't know if this is your prob or not; but something to check. as for the belts, the main serpintine belt tensioner is on your altenator, loosen the bolts and the alt will slide foward enough to slip the belt off. the powersteering belt is taken off by loosening one bolt on the pump and it too will slide enough to remove the belt. its a simple job to do and you've got all sorts of help from people on here if you run into trouble. good luck with this, man

    Re: weird noise

    sounds alot like the alternator i had take a dump on me. like snooz said the bearings could be bad but alternator could still be putting out good voltage

    mine died over the course of a week or so that i spent trying to diagnose it, finally let loose and seized up, was pretty easy to spot at that point lol

    i'm guessing it does but someone else will have to chime in w/ that one. the previous owner of my car removed all that crap before i bought it

    Your AC clutch is probably okay. Just leave the belt.
