Sounds like the same problem I'm having with my car...I'm getting this horrible smell from the exhaust and the tip is quite black as well...happens when the car has warmed up. I'm getting poor mileage also...SupraDOHC said:Yeah i backfire on shifts and have the black soot on my tip too but once my car warms up the exhaust smells horrible. When the car is cold it smells fine so thats why i think my o2 sensor is the problem. Also I have no cat so that may be part of my problem too :roll:
Would you say it's a bad O2 sensor? I have a 5M-E engine btw.
Can you buy new 02 sensor's from Toyota, if so, how much are they and are they easy to install?
