Throttle body, injector cleaning - Toyota Corolla Fielder, 1.8L, 2001

I felt that the car was going worse than before… I
bought a spray injector cleaner (Japan) 250r.

He took off the air filter casing and sprayed a little chemistry from a balloon on the damper and everything around ... tightened it with a rag ... everything sparkles!
opened the damper ... and there was darkness and horror!
in general, I cleaned everything there.

Then he started the engine and sprayed it at 2000 rpm for 30 seconds into the damper through the filter casing (it is better to remove the filter).
then he waited 5 minutes and started the engine again and until the white smoke from the muffler ran out (about 5 minutes) it didn’t turn off.
after that I reset EFI and that's it.
cars like new again!
undermines from a place very lively!

after cleaning, I changed the candles and filters (I bought them in advance)
