Default OBD & Emissions Testing

In my state the emissions test for my '98 RS is now an OBD test. My car has an intermittent misfire when it starts in damp weather and turns on the CEL light - however after several driving cycles the CEL light goes off and remains off. My question is - if the CEL light os off is there still freeze frame memory of the misfire problem in the memory? I ask since I want to pass the emissions test and want to make sure if I go for the test with the CEL light off that there won't be some stored codes in the memory that will cause me to fail the emissions test?

Should I take the fuse out to reset the memory before I go for the test?

CEL's will usually stay in the ECU's memory for 3 driving cycles. It's hard to say whether or not the code is still there without scanning it yourself. As for resetting the ECU, that would cause the readiness tests to not be completed and that's an automatic failure in most states that do OBD-II scanning.
