Question about 1998 Lexus ES 300
Black smoke is from to much fuel. You may have a bad 02 sensor. Have the codes checked first, even if the light doesn't stay on. 02 sensors are what help regulate the fuel mixture. if one or all is running lean, it is telling the computer to add more fuel. before you replace the sensor/s check for vacuum leaks. Let me know
