Also, would the leak also give me a significant loss in gas mileage? It's been really cold here and I let the car run about 5 min. or more before I take off anywhere. Usually go somewhere 3-5 times a day. I've went through 3/4 of a tank, and have only gone 110 miles.

The shifter lever has been acting up too. Sometimes, when I depress the brake and go to put it in gear, the button will not depress. So, I have to push the shift lever button to take it out of park. Then sometimes, it will work. When it does work, I push the brake in, and I here and feel a mechanical sounding click in the shifter lever. Then when I depress the button, I hear a loud electrical sounding click in the steering coulum. Any thoughts? Does some adjust need to be made? Where?

FYI- The shifter problem started right after I took my car to Tires Plus for new rubber and an alignment. Car has not been the same since I took it there. They said everything looks great though, including the brakes. Although I found one of my brakes/calipers to be hanging up. New caliper will be here today.

The shifter problem could be a bad brake switch, next time it does it (jams) have someone check to see of your brake lights are on while you have the pedal pressed. The clicking sound is the relays, which is normal.

As far as the exhaust, ours is luckily extremely easy to R&R so do the manifold gaskets first, clear codes, and then see what comes back.
