You have coil over spark plug ignition and one of your coils is bad.You need to find the bad coil and replace it.

REPLACE the EGR valve and gasket, stop being cheap. sometimes there are things that cant be fixed. It could have a micro crack in it or a bad spring. Just brake down and replace it. I have been there so many times. You smack your head into the wall for hours on something that you dance around for months. Let me know once you replace it.

There is a way to bypass it just enough to pass emissions, but I have not tried it. Check the internet, there is a shady way of doing it by rewiring through the glove box. I have a 96 Avalon with 197,000 and it is BY FAR the best car ever manufactured. I ultimately replaced the failed knock sensor and the oxygen sensor, spark plugs, etc while engine was torn apart. The car was my high school graduation present back in 02 and I wanted to keep it on the road for as long as I can. It sucks that something as simple as a knock sensor is buried deep in the engine and costs a fortune to replace, but if you are like me and know a mechanic willing to work for cash in your driveway its worth doing.

Brake loose connection between cat and exhaust manifold , it will allow exhaust gas to go out before cat , and see if it's restore the power on the engine.
If it does then your cat is clogged.
If not it's also might be Throttle Position Sensor , or Mass Air Flow Sensor.
You can't remove cat , you have to replace it if it's bad. Cat is a part of Emission control system.
