So after deciding to clean the throttle body with some throttle body cleaner, my engine's been acting up randomly.
At random times, the car would have very rough idle, and havewould sound similar to the sound of an STi. I've checked the injectors/spark plugs, but they all seem to be fine.
As mentioned above, this happens at random and often.

By chance did you check the wire set running to the spark plugs? Also yeah check for vaccum leaks egr in the back of the block by chance.

running on 3 cylinders,

if you checked ur injectors one by one,
check your park plugs and wires. both not just one or the other,

i had similar things like you, when i fixed the plugs and wires it ran super nice.

but my car's going crazy again with the idle, i suspect it might be my Coolant Temp Sensor messing with it so ima go buy another.
