Problems with Chevrolet Corsa 99 1.6

I have a Corsa 99 1.6 I do not blow a cylinder or they told me that it can be the dirty or broken injector is it true?

The first thing is to try the spark plugs with the injectors and then check the compression of the cylinders

First I would try to rule out a ignition failure that is more common.

Look at als spark plugs, take a cappuchon with the car in progress, and the cappuchon that you take out and do not change the engine rhythm indicates that spark plug fails.

look the same in the entire ignition system if everything is normal. Spark plugs coil, spark. You can go on the subject of food.

The Corsa is already soluciene the cam was broken in the last 2 cylinders was broken thanks

How such a friend .. eeh well in my experience with my corsa .. I can only tell you that if only that fault tries to change the injector .. If you have strange sounds, check the state of the camshaft or valves
