It all started with cylinder misfire codes in all cylinders, i fixed that then it went to secondary o2 sensor, replaced the sensor and cat all together, now its code cfk sensor. Could there be a reason why its just throwing code after code?

 

how many miles what year?

 

its a 99 ex with 84k on chasis and around 60k on motor... I have a spare sensor im going to switch them to see if thats it but if its not should i run through my wires and see whats wrong?

 

ok what engine do you have? it could just be that the sensors are going bad.. it also could be your pcm is going bad.. also check your battery iv seen bad batterys throw random codes cause if the pcm or the sensors dont have enough power theyll say their not working
