28k miles on mine, still the original 02 sensors and a tank of leaded blend in it's past. Knock on wood. It's still ok, of course I usually knock on the ring lands instead.

 

Oh, I know I richened it up becuase it's like 30* here. We always lean out as it gets coooold!

 

same here but my car doesnt misfire i just have CEL for like the past month dont knw what it is so im going back to stock

 

yea seems my misfires went away. havent noticed any yet. still all stock for awhile, what would cause an unusually high amount of carbon buildup on my O2 sensors? rich tune? and i have about 23k miles on my car, been misfiring since like 18-19

 

That Dejon intake will cause the car to run really rich especially right on tip in of the throttle and when you first go WOT. I would have to see street logs and a copy of your tune to see what is up.

 

Just replaced my sensor today and the car is running smooth again

Thanks for the tip! Came just in time for a couple people!!

 

yea the Sensors needing replacing was my problem, my car seems to be running minty clean since. finally

glad this thread helped some
