Why did you order an expensive MAF sensor?
Do not, do not, do not do the parts replacement routine as that gets very, very expensive, wastes a lot of time, money and can actually make things much worse.

You were advised not to replace the MAF sensor. We tried to help but you didn't take the advice for some reason. So many parts have been replaced a Pandora's Box of problems could have been introduced.
Guessing, it sounds like you've been a victim of the typical discount auto parts store who keeps selling you more and more parts. "Oh...that didn't work, eh? Well here, try this...oh...that didn't work either? Let's try this", etc. That's not diagnosis. The counter people at discount auto parts stores tend to be not very knowledgeable and are evaluated on how many parts they can sell, not how many customers they actually help to get their cars running properly.
See if you can return the MAF sensor and get your money back. Since it's already been installed though, I doubt they will allow you to return it.
To correctly solve a problem with a vehicle, the problem needs to be diagnosed and not just throw parts at it, which as I already mentioned is very, very expensive, time consuming and very frustrating, (as you've experienced).
You started out with one trouble code and now there are three. Again, so many parts have been replaced it's now very difficult to even guess which part may be defective or installed incorrectly.
The 1998-2001 Corolla's are noted for having very high oil consumption due to a defective piston design within the engine. Oil consumption can get bad enough with these engines to where it's one quart to every 100-200 miles, which can foul out the spark plugs, causing rough running, poor fuel economy, lack of power and cause the catalytic convertor to fail.
Did you read the old spark plugs?
