ok i have no clue what the problem is now. i keep getting code p0133. i replaced both o2 sensors after header install b/c they were bad. i recently replaced the drivers side header gasket and the code came back so i figured all the sealant burned off and fouled the sensor. so i replaced it. then about 3 weeks later i get the same damn code saying the sensor is slow. is the wiring bad or something because this is irritating and dont want to use 3 sensors in a month's time. any suggestions???? the d/s header doesn't leak either.

 

anybody???

 

What happens if you swap left and right? Do you still have cats?

Dave

 

have the 02 sensors deleated.

 

Not advisable since they are the front sensors.

 

i havn't tried swapping them yet but thats a good idea. and no i dont have cats.

 

so if i swap left and right ones and the same code comes up ya think its a wiring problem?

 

Could be that or PCM.

 

alright. thanks for your help.
