Default car is acting up..limp mode, flashing cel, gas gauge (related?)

my car started acting up yesterday...flashing CEL and running on 3 cylinders. It went away while I was driving (solid CEL and all 4 cylinders). I started again this morning and it was back to 3 cylinders. Same story, went away after a while.

Lunch today...car was on 3 cyl and flashing CEL for a much longer period of time.

Also noticed that my gas guage has been acting up...it said 0 miles left while I was in the drivethru, but bounced back up to 65 miles left when I was exiting (I'm sure I have at least 1/4 tank).

Possible Culprits?
Fuel Pump?
ICM?
Float in gas tank?
Related Issue (CEL and gas guage)?

No VAG here but hoping to get it scanned soon.

ICM would be my guess, but maybe something is starving the engine of fuel. what are the codes?

Default gonna meet up with a friend after work to scan it. i'll post up the details

hoping it's something easy. ICM would be my guess as this has happened before with similar symptoms.

If so, I guess it's time to change the fuel float as well.

It says low fuel even though I had about 1/4-1/8 of a tank. At some point, the car thought it was completely empty when the gauge went down to zero. Do I just need to replace the fuel float?

Side note, went to the gas station to fill up all the way and haven't had a problem from station to dinner, dinner to home, home to work.
