can someone identify this part?

hey does anyone know what this part is? i have a 1995 honda prelude si 2.3l
and can this part cause high idle? its located right behind my intake manifold it has vacuum hoses running to it and it seems when i take the one hose of my throttle body the idle goes down to where it should be but is very rough and then when i put the hose back on it goes up to about 2000rpms! this is goes to this part.


thanks in advance

MAP sensor. It can cause idle problems.

That's your MAP (manifold absolute pressure) sensor.

If your car is idling at 2K, why not just turn the idle down??

Check your throttle cable, and make sure theres no air in coolant. Your idle air control valve could also be causing this.Make sure there no vacuum leaks.

Re: can someone identify this part?

If you changed the iacv and forgot to take the radiator cap off to fill it up a bit then there will be air in your coolant. Make sure u uncap the radiator, top it off and run the car with heat on to run out all the air. If this problem started happening around same time u did that change that could be the problem.
