I experience poor acceleration with shooting sounds at times while in motion and stationary, sluggish movement, foul egg smell from the exhaust pipe.
*But when I diagnosed it, I got this result - it says catalytic converter faulty.
*Some times two nozzles will spray while two will not.
what do I do to get back my car on track now?

The foul smell is from too much fuel entering the exhaust which can be caused by an engine misfire or a faulty injector. But to be sure we have a good engine lets start with a compression test.

if okay does the engine have good park plugs, change them if needed

Next test the fuel injectors themselves, here:

Let me know what you find so I can help
