Numbers are stamped next to each spark plug hole on the engine.

is it time to replace the plugs and wires, maybe the coil?

I replaced the spark plugs and wires and still have the same problem. The Mercedes dealer wants to replace them again just to start chasing the problem, I think it is the injectors because the check engine light comes and goes every other day or weeks sometimes and the car drives very slow when that happens.

I pulled one side of the injectors off, which was very dirty on the top because the valve cover on the passenger side was leaking. Now I'm going to have to open the engine to see if any dirt went inside, any suggestions? or websites that can help me, I don't have a mechanic that I can trust to do it right and the dealer just wants to replace stuff that is not even broken.

Thanks for the help on the layout.

How many miles on the car? Sxxx?
With that many misfires the engine must be shaking a lot. Did the dealer tell you that you have the misfires?
I would recommend, before taking things off, look at the simpler stuff.
If the dealer wants the change the wire again and start troubleshooting, they may be questioning the brand of wires you installed. What brand are they?
Look at the old set of the wires for the impedance stamp (I think 2k ohms for my car) and compare to the new set. Are they close in range.

I put 12 in there, but you get the idea. Cylinder numbering is pretty much a universal constant in reciprocating internal combustion engines.

This diagram (I know, I got art skillz, y0!) is not to be confused with an engine's firing order.

The light just came on it was only once but now it is doing multiple misfiring I really think is the injectors because it doesn't stay on all the time and I had problems until I replaced the fuel filter and put in a cleaner, and replaced one injector.
I pull the injectors off and now I'm going to have to take the head off too because it was very dirty and oily around the injectors, a leak from the valve cover gasket, I don't know how many pounds of torque I need to tighten the head.

I pull the intake off and i opened, I found a lot of burned oil, it was so dirty that I think I going to have to further and open the top of the engine to look for more damages. That's probably why I have multiple misfiring, some of the spark plugs had oil on it too I just wish I had manual for repair, I look in the internet and I couldn't find it and the dealer don't even have it. I look in this website for one and not luck so far

Do a search on Ebay. Latest version of Wis/asra with epc should be available and very good price.
