Idle is bouncing and so is my voltage, need help
I NEED HELP! Me car idle is bouncing at idle around 500 to 1000 rpms. And even worse, when I am coming to a stop my voltage drops from 14.2 to 12.0 and then goes all over the place when at full stop! It even cut out on me several times. Can this be a vacuum leak, brake boost, idle air controller, I am lost and stuck, if anyone can help with this I would be very grateful, thanks guys!
