Well, I read in another post about how his car was running rich, and it was recommended to do a Balance test. So I did that, and here is what I got:

First the KOER codes were:

34 - EGR Valve Position/Pressure Feedback EGR Voltage Above Closed Limit
92 - o2 Sensor Circuit Indicates Rich -driver side(R)

Then for the Balance test:

It looked to me like it was 22. But I anm guessing that it was 20 twice.

As for the EGR, I am not really to concerned about it. But now I am stumped. Just 3 days ago the car was saying it was lean. Now it is saying that it is rich. Not only that, but with the error forCyl #2 failed, what should I check for? I am almost 100% sure I have no vacuum leaks, I have used 2 cans of Carb cleaner, and propane, and nothing is making the idle rise anywhere on the motor.

Well, I pulled out plug #2 and plug #1 to compare the two. It looks like #2 is not doing anything. It is hard to see in the pic, but the one on the left is #1 and the one on the right is #2. The plugs only have about 100 miles on them, so it is kind of hard to tell, but #2 looks brand new still.

Is there any way to check the injector to see if it is firing?
