Hello guys I get this code like once a week, but I always delete it but now that im getting 200 miles with a full tank I want to fix it. The code says this
- Catalyst Efficiency below Threshold
- Bank 2
I've been reading alot from this code and a lot of people replace the O2 sensors before...
I picked up an '02 coupe, v6 3.8l a few months back. It's running fine & passed Etest fine but only getting 13mpg city, 18mpg hiway.!
I've searched these threads but haven't found anything conclusive....Any help appreciated:-)
-no OBD error codes & it seems to run well...
I recently purchased a 1994 3.8 L V6 5 speed Mustang with 130,000 miles on it.
Oddly, it seems to run smooth, but there is a problem in, I assume, the fuel system. The car gets only 12-13 mpg, and there is an aroma of fuel that frequently comes into the passenger compartment.
I just finished...
