    it seems like i have a squeak in my pully or even might be the belts going bad. my cars been sputtering for a while and i was told it could be a 2nd ignition, with the distributor. could my truck be sputtering due to the belt not catching correctly? or could it be that anyone no?

    You gotta give us more information.

    The truck sputters when? At idle? At full throttle?

    Now, about this squeek.... how loud is it? Is it a whine, a squeek, a screach?
    When does it squeek? At idle? at full throttle? Only when you drive?

    How many miles on it?

    What type of maintenance have you done on the truck since you owned it? Do you have any maintenance records for it?

    Have you opened up the hood lately and looked around? Look at your accessory belts..... listen for the squeek (while the truck is running).

    truck has about 90 k on it, the truck when at idle does not sputter at all. it sputers as soon as i give some acceleration. and for the mainainance... it has new plugs, wires, filters, the cat is fine, no codes were thrown for an o2. so im stuck and confused now. the truck will make a screaching noise when at idle and gets worse when the belt needs to do more work. example: if i turn the ac on while in park it will start to do it worse. or when i take off it does it

    Does it get louder when the RPM's go up also.
    Mine did the same thing, started all of a sudden, I called it more of a whine, matter of fact sounded as if I had a blower from a distance. Ended up being the belt, mine went out at 27,000.
    But then again I may be off base on this.

    The squeek or whine is either a loose accessory belt or bad bearings in one of the accessory pulleys. Open up the hood - I believe you'll have 3 accessory belts (Alternator, A/C & Power steering ?).

    On each belt where there's lots of room between pulleys - grab the edges of the belt with your thumb & finger. Twist the belt. You shouldn't be able to twist the belt past perpendicular of its original position. If you can - then you need to tighten the belt. Before tightening the belts - inspect the belts & pulleys for wear. You might be better off putting new belts on.

    Or - if the belts are OK, then you probably have some bad bearings on one of the pulleys. If you take off each belt, spin the pulleys by hand and *feel* it as you spin it. If you feel any rough spots, then chances are...the pulley bearings are bad.

    Loose belts or worn bearings don't necessarily cause the truck to sputter..... The belts would fray & break first before causing load issues on the engine. So - I'm guessing you have a couple different -totally unrelated - problems to work on.

    my trd has the same noise, seems to be a whine, but it has done this from 2700 miles to 104xxx miles. never had a problem with it, and never replaced the belts. they all seem to be bullet proof and everlasting, so far. ive sprayed belt lube, and wd 40 on the suspected pulley, which made the noise go away, but it has always returned. it has never affected performance though.

    She's gone but not forgotten.
    If they were replaced just two months ago the part numbers on the belts should still be visible. Make sure the correct ones were put on. I've seen parts stores just hold the old one and new one up to each other and check length. The "angle" of the belt sides might be incorrect, that would cause squealing.

    Janster's right, bad belts or pulleys shouldn't cause the sputtering problem. Try running half a can of seafoam through the brake booster hose, put the other half in the fuel tank. Might just be clogged injectors and or a seriously gummed up intake track.

    I wanted to jout in a note on this I am having this problem aswell at the moment. With a little twist. So I went wheeling and afterwards the belt start squeeling. HAHA from the effect of belt dressing addition (sounded like nails on a chalk board).

    So I went to the dealership and the guy told me to use a wire brush and clean the teeth real well on the belt run it the turn it off and clean it some more he said should fix the issue.

    Has anyone ever heard of this method or should I just change the belt?

    none except for crappy hub caps and floor mats.
    If it sputters just when you give it acceleration, it could be a variety of things. Could be a dirty throttle body, a bad throttle position sensor, a loose or leaking vacuum line, spark plugs with an incorrect gap setting ( I know because that actually happened to me recently). As far as the sqealing, definitely sounds like a bad or slipping belt. Try adjusting the tension on it some more. Look at the underside of the belt. If it is shiny, replace it.

    My only issue is the belt squealing I sprayed sillicone spray on it and it stop squealing for a bit. The dealership service guy also told me that the truck has an auto tensioner on it. The belt is actually pretty tight on there I can't turn it perpendicular
