Don't know what type of engine
Oil, lube and filter and 20 point check they do with it, fuel injector cleaner, air filter is ok they said

You will need to remove the idle air control motor (number 2 in the picture) and clean out the passage way for it and clean it as well. Also clean the throttle body. Clean them with carb cleaner. What happens over time is they build up with carbon and it causes the idle air control motor to stick and the carbon will also restricted the air flow at idle and either one will cause the problem you are describing.

It didn't work, car still almost stalls at idle.
Have you checked for a vacuum leak? If not try plugging off the vacuum hoses one at a time and see if the idle changes. Also check the intake gasket for a leak.
