A few questions for the knowledgeable people here. What would cause the left speaker system to not work after installing a new Alternator? Also anyone else have to get their ignition barrel changed as well? Another issue is the car now will not have a clean sound when idling and sometimes slowing down, it kinda sounds like how a remote car would sound when it would slow down. I cleaned the air filter and it helped it for a day, so could it be a vacuum leak or a problem with the pcv pipe? Any help would be most informative.
