Hello,
I am trying to help my uncle out. He has a 2006 Dodge Charger and it runs really rough. At idle the RPMS are all over the place it will idle really fast, then all of a sudden the idle is rally slow. Also his dash is lit up like a Christmas tree. Every single light is illuminated, the security light, abs check engine, air bag and esp and a few others as well. My grandfather has been working on the car, and while he is not a mechanic by trade, he is very good with cars, and he thinks he narrowed the problem down to the computer, but before my uncle buys a new computer he just wanted to see what you guys think. Any help would be appreciated. Thank You in advance
Side note: He has an SXT V6 3.5 liter
