Need Help With ***MAP Sensor*** on my Lumina 1992 3.1L

[frank358fr]

Hi all,
The idle is not regular. Now my car give me the code 33(MAP sensor=signal voltage is high during engine idle.
(Note: Engine misfire or unstable idle may cause this code). My car have a unstable idle. First question: Where is the MAP sensor(with pic if it possible) and second: What I need to do to repair the map sensor??

Thanks Frank

MAP sensor is located on the back of the upper intake manifold, passenger side
As for a repair, just go to a JY and find another MAP sensor, cheapest way to fix the problem, maybe pocket a few of them


If should be on the left side of the plenum by the alternator, it will have a little clip holding it on. Will have a 3-wire clip and a vacuum hose on the bottom of it
