The 350 in my Chevy truck started revving itself to 2500 RPM yesterday when I started it up. I thought it might have been a fluke, but it is still doing it today. Never done it before. Usually fires right off to 1000-1200 and settles down immediately to 700-800. I don't like it revving so high waiting for oil pressure to come up. Anybody dealt with this?
I had the battery disconnected right before this to clean off corrosion. Could this have anything to do with it?
Thanks, Craig
