exhaust hole = this problem?

[Antigenus]

I have horrible hole(s) in my exhaust. The 2 to 1 cat that the passenger side exhaust pipe goes into has a slash thru about 80% of the pipe and then behind it, it has a ton of holes like a shotgun hit it....i tried to patch it temporarily but its not working....could this be why I am getting horrible gas mileage? its losing a ton of exhaust around that area...

Not sure, but don't forget....when your needle is on E....you can probably go another good 50 miles before the fuel light comes on.....It's just a standard thing we have with this car. Make sure you have a good gas cap...(a new one is like 20 bucks from dealer) and also make sure your CE light is not on and the 02 sensors are working properly.

Yes, It will effect the gas mileage a little. Probally the only thing to do in that case it get it fixed. I just got my big hole fixed in mine by getting a custom exhaust done up, But I can't tell you too much about improvements from just that since I got 4.44 gears put in at the same time. Good luck man.

my check engine light does come on from time to time while driving, it usually pops up once in awhile. I figured it was the exhaust leak that is causing this check engine issue.

Have you pulled the engine codes yet? (Instructions in the SVXipedia)

Likely you're getting a code for one or both of the oxygen sensors.

It more than likely is.

when I first bought my car, the CE light would come on every now and then after I went up a steep hill near the valley I live near....turned out to be two bad oxygen sensors...plus my gas mileage was bad too......I'd get that looked at.
