Saturn vue 2005 ground wire electrical issue

I wouldn't go searching for a "ground wire shorted out" until you spend the time to perform engine performance testing. It's more likely that you have a fuel and air mix ratio concern due to component concerns under the hood than a wiring concern. Diagnostic testing performed by a trained technician equipped with diagnostic equipment capable of testing the systems and individual components as well as the resource of a workshop manual and wiring diagram is needed. www.repairpal.com/repair-shops
