Ok i have been driving my car for a month with out any engine code.
Last friday i took the car for the recall on the airbag, since than the car has been parked.
Today i decided to turn it on and take it for a spin but sadly it gave a hard rough idle and it sound like misfiring.
I drove car to the garage and let it cool off. Took the spark plugs out and inspected the inside of the cylinders to check on the pistons on the passanger side since 3 of them were wet and one was dry as it never fire before.
Long story short, the piston on No. 2 Cylinder is so clean while the rest have carbon build on them
Plus i dont have engine code at all
So i dont know if i have to replace the boots and spark plug only or do i have to check the injector on that cylinder as well

I think the easiest thing to confirm is if you have spark first. Unplug the injectors turn car over and look for spark from that spark plug. Seems easier then diagnosing the injector.

I'm sure a few guys will come in to help diagnose.

It could be anything from a loose connection, to a bad sensor, injector, coil, spark plug etc. I would do one thing at a time to find the problem for sure before buying parts.

And if it's a coil, get OEM please...

Clean piston can also be from steam cleaning, caused by water entering the combustion chamber via a blown head gasket.

Check compression.

I cleaned the injectors.
Swapped the passanger spark plug with the driver side turn it on for a min. Sounded like a big misfiring on the passanger side..
Took out the spark plugs and they werent firing correctly and they all have strong fuel smell on them. Driver side is firing just fine.
So this weekend im replacing the ignition coil boots
The code of the No. 1 fuel injector malfunction came on
