I do not have my owners manual with me.
Can anyone provide a link that will specifically show in picture form what the idiot lights mean on a 2006 GMC TopKick C-4500?
This is a link to the truck photos to give you an idea of what I do with this truck.
I am trying to make it run cooler and get some better mileage.
I keep getting idiot lights coming on and off and I can't figure out what they are.
I check trouble codes and there are none.
I suspect it is a non-plugged bad fuel filter or air is getting in the fuel.
I also have low oil pressure. Or lower than nit was prior to changing the oil.
Link to truck photos:
I have looked for 3-4 days now and cannot come up with what the idiot lights are saying.
Thanks if you can provide this.
