If it is not passing because monitor is not completed and there are no trouble codes.
Start from cold engine with no more than 3/4 tank of fuel and more than 1/4. Drive it about 25 miles with at least 2 minutes of steady speeds between 35-45 mph and also the same at 50-65 mph.Then make several stop and goes,pausing about 20-30 sec when stopped.
If you turn the engine off before the monitors complete you must go thru a 6 hour cool down cycle before it will try and complete again. Then stop by an Autozone or some place that checks codes for free and have them check it and make sure no codes are stored in memory and the P1000 code has cleared. If it has cleared you should be good to go then. Plus this will make sure that it is not an issue with their inspection machine linking up with your vehicle. The only other problem it may be is if you are loosing the keep alive memory when you shut down your vehicle.That would be fuse 19 (15amp) in the underhood fuse panel.

It has nothing to do with Miles and EVERYTHING to do with Drive Cycles.. There are certain things that must be tested. Within the first 10 miles, generally speaking you are going to complete the Drive Cycle requirements for ALL the tests except for 2-3. The EVAP/ O2 normally the last ones to get cleared.
Your Vehicle is a 1999 which means that you can pass the I/M test with 2 lights "NOT READY". The EVAP is going to take longer than a few miles, you must fill up your car with fuel above the 3/4 mark and then it has to go below I believe it is 1/2.
A few suggestions that can help a fresh oil change.I have seen dirty oil peg out the gas analyzer 9999 HC. Replacing the PCV valve if the valve is stuck open all the time it is pulling oil into the intake side of the engine and into the combustion chamber. Hope this helps.
It sounds like the battery is starting to go. You can take it in to get it tested to make sure. Some places (like Wal-mart) do free battery testing. If this is the original battery, five years old, it wouldn't be surprising that it is starting to go.
everthing effects the reading. pedal position, rpm load engine temp. air temp. all that stuff you added was just a waste of time and money. What you should of done wa diagnosed it correctly so your not cheating an emission test. Since barley failed the first time I would of recommended a tunup if not done in 40,000 miles. I would have looked at the scanner data to see if the inputs were correct. Iwould have serviced the oil if its been awhile. If everything checked out i would of recommended a catalytic converter. But there are 3 test to determine if the cat is dead we do first. If your car was barley failing and you needed a tunup and the cat was still good the need for a tuneup could toast the cat within a couple weeks.
Emission standards are so low these days that its almost impossible depending which state you are in to get this vehicle to pass. For this vehicle to pass the engine itself have to be in tip top shape and the computer must function properly. I've had a problem like this with a 85 Toyota land cruiser and I have change all those things you change except the timing chain, IAC and MAP and the problem was the computer got a manufactured one and BINGO it passed emission test here in NY. Two choices try the computer or let it sit for a few more years then it becomes a classic after 25 yrs and it doesn't need emissions NO more just safety, like brake lights seat belts etc. Good Luck and thanks for using FIX YA
