Im honestly pointing to bad delete programming, it makes
me so frustrated when most all mechanics will say delete programming cant harm an engine, what a load of shi#t. I bought the truck, the guy deleted it 6 months before that(my only concern with the truck). I just recently got a computer/adapter and programs. How can I extract the delete data from insite? And would you be able to review it?
