This PDF is very informative, however I am on a time constraint. I need to get my vehicle smogged and don't know if I will pass with the strong exhaust odor. I have looked at various results I got from about 30 minutes of running/driving time. I see variations between banks 1 and 2 O2 sensors, knock counts of 9081, timing which seems to vary drastically during my test between approx. 8-48 degrees. Despite this, the car is running great and NO DTC's reporting except CAGS which I eliminated shortly after taking delivery of vehicle. Disconnecting the plug on transmission was recommended by manager of St. Therese plant at the time. I could look in several directions by reading this report, but don't want to go the wrong way. Car has original exhaust system and O2 sensors with 68k original miles. The original Opti was replaced several years ago by an MSD unit and haven't had an issue since with smogging car. Only modifications done are to the ignition and air intake (coil, opti, plugs, MSD 6AL, MSD plug wires, and NGK plugs, K&N FIPK, Jet Performance Fan switch).
Bottom line is I could really use some help to decipher my results. Don't know what parameters to look at specifically, and what is considered "normal" or "abnormal". If I had any serious problems, I would think I would be seeing DTC'S.
Just concerned with strong exhaust and passing smog test. Thanks again for your help!
