These codes clear but reset almost as soon as I start driving. How do I repair the problem?

Sorry about this my eyes are deceiving me thought it said 86 jag. Ok 46 & 47 both deal with idle air control valve. It diagnosed with voltage see pic try cleaning it and throttle plate on both sides first with choke cleaner. It may straighten up like tht and check for vacuum leaks as well. Sorry about the first tow screw-ups. These are taken at the BLUE ecm connector it can be a bad ecm as well. Or a short in wire.
