Hello I have a 2008 hoe ltz with the 5.3 flex fuel. I think I’m having an issue with the ecm or pcm. I know there is a grounding problem because I can see it when the headlights are on. The passenger side headlight is dimmer and you can see the running light and the bright is barely lit but it’s getting some voltage. The pass. headlight gets dimmer when I turn the fogs on it also messes with the driver mirror signal when the fogs are on. It stays dimly lit between flashing when the fogs are on turn them off and it’s fine. I also keep getting a code for the maf which I replaced twice already. I know it has to be a grounding problem and I already replaced the negative terminal along with adding a new ground from engine to firewall. Any ideas!??
