Apparently a P1000 is an incomplete monitor testing...basically saying the ECM hasn't gone thru a complete drive cycle to check all it's systems. Supposedly you have to perform a drive cycle: 25mph for 5 miles and then 55mph for 5 miles or some ****, sounds weird and tough to do. That's what I found doing some research.

No, all it takes is some drive cycles. You don't have to go 25. You just need to drive. Its a code that is saved so you can't go to an inspection station, unplug your battery to clear the codes, and then get inspected with no CEL light. Just drive to a store a few miles....then turn the car off do some shopping...then drive home. It will clear the code. It's how I cleared it for inspection when I swapped batteries between my mustangs.
