It just seems odd though, and I know it happens all the time..."the light just came on" But usually something changes, sounds, smells, lurching, high idle, smoke etc. So was it actually a bad O2 for you? Or was it just a glitch in the ECU? My books are showing that code 14 for him is igniter and coil as he said, and 26 can be a multitude of things, all pricey. I`m gonna go out on a limb and agree with the O2 censor here, but I havent a clue why it would come up with 14 as well, lets hope its just showing up as you said.
