I have a 94 ls and when you start it it will idle back and forth from 2500 to 1500rpms and i unplugged the map sensor and the other sensor close on the side of the intake manifold and it will idle really low and sounds like it might be missing idk im new to hondas its my first one i would greatly appreciate any help thanks

 

02sensor, If your new I wouldnt be unplugging things you could cause big problems.. If your talking the 2 sensors on the TB one would be your MAP sensor that measures the intake manifold pressure, other would be your TPS ( throttle postion sensor) and that tells the ECU what postion the TB plate is at so it know how much fuel to add same with the map.
