Emissions Monitors - 2 won't reset. :(

Hello

I have searched and found that after you unplug your battery you will have to perform a drive cycle to reset all 8 emissions monitors. I have driven the car for 1000 miles. I have performed the drive cycle multiple times and I STILL can't get the 2 catalytic monitors to reset.

What am I doing wrong?

8:30am - 65 degrees. Car in Garage. Cold Start.
Car starts & runs at idle for 3.5 mins.

Drive out of neighborhood. Never exceeding 3k rpm or 30mph.
Establish cruise speed of 20-30 mph for 3.5 mins. One stop sign and one stoplight. All under 3k rpm.

Enter freeway. Gradually increase speed up to 55mph (under 3krpm). Set cruise for 55mph. 23mins. Exit freeway. Slow to stop.

Let car idle for 5 mins.

From idle... Increase speed to 20-30mph (under 3k) for 3.5 mins.

Enter Freeway gradually gain speed up to 55mph for 22.5 mins (all under 3k rpm.

Exit freeway... Let car idle for 5 mins.

Check monitors...

Same 2 monitors still NOT reset.

What am I'm doing wrong?

Thanks,
Ted
