hello, if i were to have a vacuum leak or turbo leak would the engine light pop up?.

The reason why im asking this is because, the engine starts to shake a little bit after its warm, and i can hear a hissing sound every now and then if i listen closely. the idle moves a little bit from 600 -800 rpm. But my engine check light is not on at all.
im new to cars in general and this supra is my first car, and advice would be great thx.

no, if it's JUST a small vaccum leak, the check engine light usually doesn't come on.. unless it's causing something else to fail... find the vac leak and fix it.
