Hey, so my rx8 got a new engine put in about 1500 miles ago. It has an o2 sensor out that's not reading so it's been running rich for a little. I just noticed a little too much smoke blowing out the exhaust and wondering if it could be from it running rich? Or could it be another problem? Is it okay to drive on or will I cause more problems? any advice or ideas to whats going on would be very helpful, thanks a lot.

I think its normal unless you have a CEL on, lately waking up around here (Northern NJ) its like 40 degrees in the morning and when i start up a puff of smoke shoots out from both tips. I give it a couple of minutes to warm up and it gradually gets less and less and to the point its not even visible.

you should be ok ... has it got colder where you are it might just be simple water in the tailpipes ...

Most likely water with a tad of oil just burning off. If you had a midpipe I'd be a different story lol like me.

winters begun here and it's got a little colder; but, it was during the day when I noticed the extra bit of smoke. well if it's nothing... sounds good guys, thanks a lot I really appreciate the help. How long do you think I should wait to replace the o2 sensor?

Well my stock cat went out at 18,900 miles. Idk about the o2 going out tho?

I would replace the o2 sensor as soon as you can, don't exactly need to rush but i would get it done
