Hi everyone. I have saungyong rexton 3.2 Benz 2006. The trouble is that the engine after starting is not stable with blue smoke sometimes. In the scanner the line of the o2 sensor is not well and after replacement the two sensors and after clean the injectors and replace the coils and plugs-still the same after all. The co level is more than 2.5 percent. Some has this problem before in the same car? Thank you. Rot

Make sure you're using the recommended spark plugs. When my car did that, I had put Bosch Platinum Plus-4 plugs in and got that same problem. Turns out the plugs are too hot and cause it to fire prematurely and kick the misfire code.

1- check there is spark come from spark wires
2- check the fire timing by looking for every wire in the right place
3- check there is injector signl
4- check for any vacuom leak
5- try to clean the MAF by brake and parts cleaner
6- try to reset all the code and see what will come after that

The AF sensors are uupstream and the O2 down stream. The car' s computer tests them and it is saying your cats are bad. If you have a scan tool you could look at the data and see what the sensors are seeing. The Af sensors are the ones that control the fuel ratio in the car while the O2's just watch. AF's would be the one to change but there is no garuatee that the codes won't come back.
