    Sounds like your idler pulley, or possibly alternator pulley. Describe the other noise.

    i thought it was oil on the pulley but i took some degreaser to it and no luck with that.. it sounds like litterally a bird chirping when its just idling ( like a high pitched noise )...

    i also had another question.. is there anyway to get rid of the "skip shift".. evertime i want to go from 1st to 2nd the damn thing comes on and if i try to shift it grinds up my clutch...so i have to wait for the RPM's to get real low before i can shift to 2nd.

    does the sound go away when the car is nice and warm? could be something simple like a belt, mine used to make a chrip like you are describing.

    and for the skip shift you have a few options,
    get it tuned out
    buy one of those "skip shift eliminators"
    hook up a resistor to it... Annoying "skip Shift"


    cheers

    mine did the same thing. First thing that i did was to pull the AC fuse (so you dont send a code or something like that) and then take the AC Belt off completely. Its easy to do if it goes away then it was either your AC tensioner or the AC compressor. If it wasn't it than at least you know something else beside that is squeaking.. Also if it is your belt and if you don't care about how clean your engine bay is, pour baby powder ( yes, baby powder) on the belt. seriously, it will stop it.. thats my .02

    Just a thought, depending on the mileage you have you might try some water pump lubicant. They make verious types for both standard coolant and synthetics. Just a guess but it maybe you water pump showing its age. Sometimes if a car sits for long periods of time this noise can happen too. It wont hurt to try mine did the samething and as soon as I added the lubricant to my coolent the sound stoppped and never came back. Just something to try.

    Never heard of this....


    I have 157k and I have replaced everything.

    Idler make the most noise, one for the main drive one for the AC drive. The AC drive you can regrease. The AC tensioner gave a helleva whine to it especially if drove on wet roads.

    Yeah it was usually more common on the older v8s and v6s but it sometimes still can happen. Sometimes it can be the only sign before the water pump fails. It may not be the problem but like I said the luricant wont harm the pump so if that isnt the trouble you've lost nothing but a couple bucks for adding the lube. Also I've purchased parts that where bad right off the shelf.
    Some rebuilders use substandard aftermarket parts in rebuilds. Even used original parts. I worked for a shop that did this a few years back and their policy was (we don't make money if every part is a new part). But this seems more common in starter and alts though. Another thing is if you live in an area that uses salt on the roads in winter. It seems the 93-02 f-bodies have a tendancy to "scoop" salty mist from cars in front of you and deposit it right on the front of the engine. Salt is very hard on rubber seals and rotating parts. I have a 2001 Camaro that sits most of winter but I have run it in the winter. Then found in the spring time salt had built up just about everywhere forward of the engine block. Even nearly choking out my rad. But I could go on and on. If you've tried everything else and the sound don't go away give the lube a shot, nothin to lose. I don't know how experianced you are with the f-body but I've owned 4 two 3rd gens and 2 4th gens and never owned a vehicle that wasn't a GM. Not to poke at you but just because you never heard of something don't mean it don't exist. Ref Advanced Auto. The advise was also for Hot-Sause-LOL. Don't mean to tick you off though.

    9 out of 10 times it'll be a pulley on these cars. Take a long handled screwdriver and put the handle end up to your ear and touch the tip near or on the base of all the pulleys and if it's a pulley you'll know it.


    disclaimer: Be very careful using the redneck stethoscope and don't get your face or the screwdriver caught in the belt. Both scenario's end badly. A length of busted broom handle works also.

    Agreed, my car does the same bird chirp noise. It is the AC clutch that is the culprit, so it's either get a new AC compressor, or rip it out.....

    LOL. Or you can actually get a stethoscope made for that purpose at Harbor Frieght for $6 and save your face and digits.

    another angle on the chirp. a while back i spun a conecting rod bering on a mopar 383 by over reving it and it made a loud chirping noise. it could be something from the rotating assambly. dose the chirp increase with the rpm of the motor? does it sound internal?
