Default Many Codes - Misfire - Loss Power

Gray 2005 Saturn Ion II (2.2L, Manual, ABS/Trac)

My wife was driving my gray Ion. Out of the blue driving down the freeway it lost power. Almost sounded like misfire, really rough idle. We swapped cars and when I drove it, I noticed the loss of power right away. Around ~2200 RPM it would feel more back to its normal power, but not completely. I could get it up to 70mph but it was weak, I had to leave it in 4th gear.
If I leave it to idle long enough the engine light will stay on. But if I hit the throttle (moving or parked) it will start blinking rapidly.
The engine light has been on since I bought it. The code was a bad cat but I have never bothered to replace it, as it seems to run just fine. The guy I bought it from sold it for the same issue that I am having now. He tried to fix it but gave up and left it sit for a year. When I started it up to test drive it, it was running like normal. I bought it at 119k miles and it has 146k now, and now this same problem came back.


So far what I have checked….

Fuel Pressure - 54-58 PSI
Fuel Injector – 14 OHM (seems to have a weird reading)
Compression – varies but mostly at 210 PSI

Switch parts with my teal Ion
ICM/Coil and Spark plugs on teal Ion, runs fine.
I don’t know what else to check. Anything you recommend?

The only weird thing I’ve noticed is that when I took the spark plugs out of my gray ion (the one I’m having this issue with) one of the spark plugs is wet, on 4 (by the transaxle end). I put it in my teal Ion and drove it for a half a mile. Took it out and all 4 are dry. What could cause that?

I got 16 codes, bottom is first to top is the last. I don’t what is these mean. History, currently history,Intermittent, Comfirmed, Pending.

P0496 - Evaporative Emission System High Purge Flow - Pending
P0442 - Evaporative Emission System Leak Detected (Small Leak) - Pending
P0420 - Catalyst System Efficiency Below Threshold Bank 1 - Pending

P0300 - Random - Multiple Misfire Detected - Current History MIL
