Another CO Adjustment Question.

After correcting my CO adjustment a month ago everything was working just fine until a week ago when I noticed the engine was hard to start, hot or cold, and a slight rough idle as well. I decided to check my duty cycle reading again this evening and found it to be sitting at 92% flat!! Fortunately it is not running that lean, I can tell by the smell of the exaust. Is this a trouble code? I have tested the battery voltage, the OVP relay, the EHA and the idle air valve,,,, All of these seem to be functioning properly. What else should I be looking at??? Your suggestions will be greatly appreciated.
