Check the engine compression.
Check for vacuum leakages.
Do you have coolant losses and overheating issues?

All good except it has a low compression on the 4th cylinder, I was guessin that the injectors are clogged or just the ecu isnt telling them to spray

Low compression can result in misfiring. How much lower than others?

Guessing can be a waste of time and money. Test them to confirm. Try swapping the injectors.
