voltage fluctuation on cold startup
So after colder nights in arizona, when I start my truck up the voltage on the battery gauge fluctuates. I can watch it build back up to full power after it has started the truck, then it fluctuates about 1/4" back and forth for about 30 seconds then runs fine. When the voltage is fluctuating, you can hear it also in the way it idles, and even see a teeny bit of idle fluctuation as well. It doesnt fluctuate really fast, but maybe a couple times a second, at the fastest, and its rythmic on how it fluctuates. It does NOT do this after a warm night, so Im thinking it may have something to do with a GPR cycling on and off, but the wait to start light doesnt come on after it has origionally gone off. It also seems to do it longer the colder it has been.
This problem sound familiar to anyone? It getting really annoying and would like to get it fixed. Im sure my neighbors would like it as well, cause it loud as my truck is, and as early as I leave, Im sure a nice smooth idle on startup would be less annoying haha
