when driven now, loss of power, still makes the same noise, louder.

the noise increases with rpms, will not idle in park or drive, have to give it gas to keep it going.

personally, an with my lack of any mechanical training, it sounds like something engine related

the sound gets louder and faster as rpms increase, and the sqeaking is intermittant, and doesn't sound like a belt.

as far as the A/C compressor is concerned...i wasn't running A/C at the time (ilive in western washington, it doesn't get much use

), if that makes a difference.

Alternator was just changed, but it was a rebuild. when you say " blew up," how literal are you being? there were no exploding-type noises, no shrapnel, and nothing that sounded to me like a belt flying off into infinity

ok,the idler pulley on the front of the a/c clutch can go bad causing the symptoms you see.i doubt it's the alt or battery[voltage has to get way lower than that necess to start car before affecting running] but it could be a bad load of gas[water contamination] or a blocked fuel filter.
