That's what I thought too but it's been gong on for about 3 weeks an have already tried to relearn it twice.... I may me doing something wrong tho.... I'll give it another shot...

hmm. I just changed my cats due to the p0430 code it gave me. Mechanic said it was not related to the idle problem i was having, yet, no issue after new cats were installed. truck runs like its new! Maybe go to an exhause shop and get them to infared camera the inside of your cats to see if there clogged?
