Dont mean to throw em at you like this, but i've tried lookin on this site b4 posting them...

1. A/C Compressor Squeaks like hell, at least i think the squeaking noise is coming from there, thats where it sounds like. I just replaced the belt so it cant be that. Ive read somewhere it might be the pulley bearing or something? Well that doesnt tell me how to fix the problem which im trying to do. Anyone help on this one?

2. Car will stall sometimes after sitting at a stop light. When i give it gas after letting my foot off the brake my engine wants to hesitate and sometimes will shut off. I think it might be a vacumn leak but i've checked with carb cleaner everywhere and hear no sign of any??? Can anyone help me fix this problem?

Thanks in advance for your help

 

It could definitely be a bearing going out on the AC compressor. Just go to the parts store and see if they have the bearings seperate or you could by a remanufactured one for $200-300 probably. As for the hesitation, it could be a vacuum leak but since you said you checked for that already, I'd just do a tune up on it; most of the time it's just a set of plugs that need replacement.
