What would cause my Jeep to have sudden HORRIBLE gas mileage?
I have a 2000 Jeep Cherokee. I kept failing CA Smog. It turns I had a leak where two of exhaust pipes were connected. I took it to a shop where they cut out the flanges and put a strait pipe in. Well, I passed smog but after all that my gas milage was terrible. I’m getting 12 MPG.
What could have happened? How can I fix this?
