Engine Performance problem
1999 Audi A6 6 cyl Four Wheel Drive Automatic 104000 miles

This is the code that AutoZone is giving me. But I keep getting this code and dont know what to do. I have replaced the ignition coil, new spark plugs, moved the #2 fuel injector to the #1 slot and still the same code comes on. I might just need new spark plug wires but I was told the were fine. The car also smells like its burning oil, I guess that cause its licking oil from somewhere underneath or rear. I just dont know what to do. The car wheel also rattles at speeds above 60mph.

Do you
have the same problem?

I checked it to day at first it gradually went up to 150psi and then went to 120 and stopped then I did it again and it gradually went to 150 and stayed. I did this about 4 times and all had the same results.
