• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

i have had my car for a while it has a 3.4 pulley with colder plugs and 180 stat. it has a full k&n intake with a u bend delete and resonator delete also. but my car when im racing once i hit 80 85 it will like cut out but then jsut keep going, my car says i need an o2 sensor and thats al lthat pops up. will this cause my car to do that or is that kr?
 


If you don't have a tune and haven't been tuned...you are definitely having some KR. Get a tune or a tuned PCM, I would recommend a tuner over the tuned PCM. A bad O2 sensor can contribute to your problems. Replace the O2 sensor.
