[QUOTE="Mort, post: 261497, member: 361"] Back at it....OBD reader finally comes in....P2196 code...02 sensor signal\stuck rich bank1 sensor1 Read up on possible causes...ah...gonna have to do process of elimination as there are several possibilities as to what can be wrong. Gonna be fun. Just to summarize, before I change the plugs, my CEL was flashing, it no longer flashes, but stays on. backfires running at first, idles rough. No visible smoke. I am suspecting the following. -possible plugged cat -vct solenoids are bad -O2 sensor failure -Maybe MAF sensor I'm not sold on the injector being stuck open, the reason, no smoke out of the exhaust. I read up on another site of a guy had a P2196 code, went to the extreme of putting a new motor in, reason he put new motor is was he had low compression, so he figured it was due, still got the same code, went through the process of elimination, checked everything, was stumped, then decide to just take the 02 sensor out, but leave it plug in.....viola...motor run fine, and no code...go figure. Moral of the story: he had a bad catty converter. [/QUOTE]
