Engine Running Weird
My car started running weird this morning. I had been driving with a CEL light for awhile. The CEL is because when the muffler shop made my exhaust they put the rear O2 sensor in front of the cat. So, last night I reset it and went into the house. This morning it was running fine for about 10 minutes, then the CEL came on and the car would sputter when I pressed about 3/4 on the throttle. After the sputtering the CEL would flash a few times, then go out. I looked at me A/F gauge and it was sitting all the way on lean. When I would give it 3/4 throttle and while sputtering the A/F would read ritch. I think maybe my O2 is bad now. It's still too early for Autozone to be open so I can get the codes read. What do you think it is?

I have a Faze A/F Meter, Narrowband's the cheap ones right? laugh.gif:
Actually it was right above freezing this morning. What made me wonder though was that the A/F wasn't scanning like it normally does. However, when I got to work I shut the car off and restarted it the A/F started scanning like normal.

Well it ran fine on the way home from work. I'm guessing it's cause I didn't warm it up this morning. I still need to get a new exhaust though, cat's definately gone bad(again!).
