My 02 2.7 has the CEL coming on and off with different fueling( so it seems ) the wife gets gas when ever its needed and not always at the same gas station,..But in the same town Tucson,az ...So maybe the additives or maybe gas cap..?? the CEL is on more than off even with 1 02 cable changed out,I think its on 60% of the time ??? Thanks Frank
