I have an old 89 Civic Wagon 5 sp, I would like to modify it and run it slightly lean. I have 3 pin PA sensor, One end/centre pin measure about 3K, other end/centre pin measure about 5K, Would you tell me more about how that how I connect those potentiometer?
Thanks

This sensor, depending on what your particular manufacturer calls it, controls the fuel mixture by sensing the ambient pressure at what ever altitude you are driving. The higher the altitude the leaner the fuel mixture.
All you do is put a 25k potentiometer switch on it and turn it down till the idle speed changes. All you are doing is telling the ECU you are driving at a higher altitude than you really are. There are no problems with warning lights or ecu problems this way.
Just be cautious you don't do to far or you can burn pistons or valves due to higher cylinder temperatures.
