Marc emailed saying the anti backfire mode was enabled. Hmm. The only thing that has changed is the top end porting and rutune. I double checked all the header bolts etc when underneath but I did remove the exhaust and reinstall it. I'll be doing fuel filter and while I'm underneath I'll check the exhaust connections.
Would o2s throw a code if going bad ? |

Not if one is slow, You need to have it on a scanner to check them.

Hmm any special scanner ? I have a basic one but doesn't show O2 readings. My brother has one with a screen that does but not sure if it works with obd1? I may as well change them any reccomendations on this forum to generally stick with ? |

I was having some backfire on rapid deceleration and it was having a hard time stabilizing rpms at the same time, and some lag in light throttle response. I have a scanner that I can watch and capture data. What I saw was the right 02 was reacting very slow and not cross counting as fast as the left and the numbers were off compared the the other. I replaced both 02's got them from Jerry's car runs great now.
Let me add I still have secondary's and high flow cats this was on my 91.
