When I took my CL in for inspection, there were three things that were not set. EGR, EVAP, and Catalyst. Thanks to the forum, I was directed to the owners manual and introduced to the "Drive Cycle". Friday I replaced the battery, and Saturday we took the car for the Drive Cycle. My wife had the timer going, and I was concentrating on doing it correctly. Brought it in today, and everything went perfectly. Times like this, I really love the forums. Very informative posts. Now I have to fix the power steering pump, since it's making noise. It didn't until I replaced the belt and tightened the pulley. So, it looks like the seal, and possibly a return hose, since the fluid is getting frothy.
