Well i have a 1992 for explorer 4.0 all lights seem to dim kinda surging at idle or coming to a stop. Has new battery, battery cables nice and tight new alternator. my Volt gauge on my cluster jumps from 12 to 14 volts. battery light flashes seems to be getting worse. Was having similar issue about 1 year ago found a injector giving up. Replaced injector and worked good for a while Wondering is it common to have that issue with injetors causing these issues. Doesnt seem likes its missing firing

Based on the description provided, it sounds to me like you have a vacuum leak. Since you mention the charging system though, is there a reason you think it may be charging system related? How low is the engine speed dropping at idle? When you mention "dim kinda surging" are you saying the surging is subtle, or the lights dim?
