Misfire codes C70 1998

It is the front O2 sensor that detects a misfire! Sort of. The sensor sends the info to the computer, because each pulse from the cylinders is slightly different depending on the amount of spent gases and unburned fuel being detected.

The ECU then determines which cyl is not burning fuel by the crank position and sets the code. Pretty slick!!
