Default

With the gauges acting the way they are and the rpm issue, I would check your connection at the battery first. Make sure they are tight and do not have any corrosion. Also you may check your grounds in the engine bay. There is one on the back of the d. side head, and one on the d side frame rail below the abs module. I am sure there are some more but cannot think of where they are at right now. Maybe someone else can chime in also.
