When you get any code,it does not tell you anything is wrong or what to replace

You use the code to diagnose the part of the system,that set the code

Most likely cause for an O2 Code, is a vacuum leak,which drives the sensor lean, and it goes out of range. Thus the code is set (Education is the Key )

You have at least two O2 sensors for every single exhaust,four or more for dual exhaust.

Your current code may be a new problem

Where is the map sensor located on a 2001 hyundai accent gs?

Your engine has likely worn out. You are describing the situation when the piston rings are so heavily worn that gas pressure forces itself into the engine sump, pressurizing the lower oil case, and forcing itself into the evaporation system, which then makes its way to the air filter housing.

I advise doing a compression check on the engine at your local garage and repairing or replacing the engine if necessary.

I have a 1999 hyundai accent and the car stalls when driveing it, is their a fuse that controlls the spark for the timming on the engine. We have already changed the coil pack, sparkplug wires and the...

No ,,No fuse controling spark,,Your coil pack on top of motor could be cracked and causeing this or your fuel filter, or fuel pump, you could get a pressure test done to your pump at a garage,Check your spark plugs,change them if you can, change the fuel filter a good place to start,,,,,,,,,,,,Also is there a check engine lite on in the dash cluster? If so go to Auto Zone parts store and get a code scan done its free,,than they will give you a print out of the codes and what needs to be replaced,,most vehecles in the 90,s have or need 02 sensors that control your air fuel mixture,,,were talking gas mileage here.
