Hi there, i'm cleaning my TBI, and i can't figure out what this parts are for...

The one on the left i remove it from the valve cover and a hose went to the front of TBI, the other one is from one side of the TBI\

Any help will be appreciate

That is your PCV valve on the left, for Positive Crankcase Ventilation.
&
Throttle Position Sensor on the right, TPS.
Don't soak the TPS in any fluid, that can render it inoperable.

Yeah my dad cleaned his TPS the other day and it ended up going out. Haha. he used electrical cleaner and wd-40. I almost smacked him.

ok thanks for the advice, i already clean my TBI but i think im going to replace the tps, pcv and the iac, because the car is up and down in the rev.
