injector problem

hello friends ... 2 of the injectors were repaired (was leaking from the bottom) .. there was a slight flickering of the idle and the engine warning light came on. He applied injector opener with a primitive method such as .. a method I have not seen before was not a solution, of course, the engine started to work a little louder ... my questions about this issue;

1-did this process harm?
2-Does this stamp repair block the injector nozzle?
3- Is there a simple solution to this problem? because the pumpers are talking about the numbers over a thousand TL ..
4- Does this problem work for me in this way?

thanks..

The change of the stamp does not damage the injector because it is a primitive and unnecessary method because the filler presses liquid to the injectors of virgin material near the tip of the injector.If there is nothing but a useless time loss in the injector, which is nothing but a naughty obstacle or a functioning injector. Replace the complete pump to a competent pump through its job, I made 206 hdi min 4, reset 500 liras if you don't want the masters' tampering tool pug branded vehicles are a little kind if there is a problem.
