my autometer air fuel meter gauge is reading very rich lately, i know that it only had the correct reading at WOT so i tried that and it and very rich, now its even rich when im im not at wot. it only sometimes does the whole spectrum of color thing that it does. i checked my CAI and it looked fine. i changed it to my shortram just to test it out, and its the same thing. my filters are clean and all. does anyone know what it could be? thank you.

check the wiring for your a/f guage first. make sure your ground is cleaned up
