exhaust hole = this problem?
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.

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.

oxygen sensors dealer only? I was under my car yesterday and they looked fried. If im replacing the manifold to the 2to1 cat I might as well replace the o2 sensors also huh? Let me know how much the sensors are if you know off the top of your head.

If the sensor tests bad, switch to a MAPP gas or Oxy/Acetylene torch. Heat the perforated area and then remove the heat and blast the sensor with compressed air. Retest, repeat cleaning if necessary, retest. If it does not test normal at this point, replace it. Most sensors that are fouled can be cleaned successfully. When replacing a sensor, don't miss the opportunity to use the test above on the replacement. This will calibrate your evaluation skills and save you money in the future. There is almost always *no* benefit in replacing an oxygen sensor that will pass the test in the first paragraph. Doug

Doug you are the man, im gonna do that. My dad owns a water systems company and we have multiple copies of all those tools you described. I will clean them and test them asap. Is this whats is leading to my rough idling? (besides the huge hole in my exhaust) or should I replace the injectors also?

I would change one thing at a time and reset the ECU in between. As for a rough idle, that can be caused by many things. Vacuum leak, fuel system problem (not necessarily injectors), clogged throttle body, etc. I highly doubt that at idle, an exhaust leak after the O2 sensors would have any affect on idle performance. You car would probably benefit from a total fuel system service. Call around to the shops and see who performs the following: Fuel pump pressure AND volume test. Pressure regulator test. Isolated fuel line cleaning. De-carbonizing through the fuel injector rail and intake. Not many shops get that involved with a fuel service but it will breath new life into your engine if they do.
