So heres what happening...whenever i stop and i start to idle, my truck's RPMs drop way down and the whole thing "bogs" for maybe a second, the voltage meter on the dash also drops maybe one notch then goes back up, but ive noticed that it has dropped maybe one full notch just today alone......I dont know what could be causing this, maybe my alternator is finally dieing? ive got a sub system hooked up to my truck and im going to disconnect it tommorow and take it out to see if that helps any (im selling my sub and amp anyway lol) any advice?
