battery voltage while running
Well I got through running codes on my car tonite with my new autoxray 300 scanner. No codes are stored and everything seems ok. My question is shouldn't the battery read higher than 13.2 volts while running. I"m wondering if this is contributing to my loss of power and how the car seems to be running lean. Also while in park the car won't rev over 3600 rpm or so. On the road it runs great and I have no idea. I changed the fuel filter tonite and all the plugs and wires are new. Where do I go from here? I'm thinking fuel pressure test.
