okay my caddy has had some problems for the past 3 months. idler pulley, compressor,belts etc. now i think my alternator is starting to take a dump on me. my voltage meter is reading 13.4 volts and last week or so it read 14.6, and when i went to start my car earlier it fired then stalled then i tried to start it again and it ran fine, also noticed not starting as strong. And sometimes my car gets like a weird egg smell to it and it makes a little squeaking sound but not bad and a little rattle. Any help would be much appreciated.

 

13.4 volts meanings alternators working. Slow starting normally battery, cables, connections, or starter. Can't help with noise can't hear it.
