Next time, remember: Autozone pulls codes for free.

 

I have a code reader. Problem is, one of the first one that comes back is the O2 sensor. That's the main reason why I was replacing it. Apparently it was throwing an O2 code since so much unburned fuel was getting through the cylinders. Then I guess the misfires came in when the plugs started getting saturated with gas and carbon.

 

Gotcha! That explains the O2 sensor as well. Now we have to figure out why it's running rich.

 

Because of the bad MAF (I hope!... should know today when the new one arrives in the mailbox...)
