Renault 11 Txe 3 cylinders

Hello good! It is my first time here and consults them for my car that is a few days ago that is as if it were in 3 cylinders. I clean the spark plugs that seem to be fine and continue to work badly.
any advice ?? Because the truth is that I don't know what else to do and I don't have $$$$ for the mechanic. M,
thank you very much !!!!

If it is in three cylinders, you have to check the spark plug cables, the distributor or delco lid, and rotor, as well as the state of the coil, the best way to check this problem is to isolate the problem, that is to say with the engine in progress, disconnect a cable and see how the engine works, at some point you will notice that you take out a cable and the engine is running the same as this and that is the cylinder. already discovered which one is dedicated to seeing what he lacks.

Thank you very much for the answer and suggestion.
I do that and tell you what happened.
Greetings.
