Hi,
I'm new to the FTE forum and I was wondering if you could give me a little knowledge. I have a 1985 F-150 with a '91 5.0 HO in it. When warm, the idle surges from about 500 RPM to 750-800 RPM. I'm wondering if it might be O2 sensor but maybe you know of something I'm not thinking of...also smells like it might be running a little rich (no cats.) Anything is appreciated!
