CEL 67 : Catalyst system Efficiency Below Threshold malfunctioning or defective catalyst system

 

ever try replacing the cat?

 

not yet......anyone have that they dont want?

 

yes, but it'll still make you throw a code 67

 

Just buy a test pipe...

 

I've got an ITR cat that I can sell.

I don't have any use for it, so expect it to go for pretty cheap.

 

i feel ya bro. I think my O2 is bad too. Im getting about 15-16mpg right now, 20 on the highway. I havn't been able to swap out my o2 yet.
