I installed a dynomax superturbo catback today, as soon as I turned the jeep on I got a check engine light.
I ran the codes and got a 0137 and 0138, being a O2 problem. I was wanting to change the O2 sensor out because I get a consistant 9.26 miles per gallon.
How do I change the o2 sensor, I believe it is on the exhaust manifold but do I have to gain access from under the jeep? How hard is it to change?
Just for reference this is a 1996 4x4 sport 4.0 auto.
