Does anyone know where you can purchase a MAP sensor- new for a 1986 Chevy Camaro w/2.8L V6 engine? No one I can locate appears to sell this particular part. Need your help.

That looks like the one. The only difference I can see is a 3-prong plug. The one on my car has a 4-prong plug. What the 4th wire is for I don't know. I have a 2.8L V6 173 ci engine.

If you know why mine has a 4th wire let me know. Maybe I can change it to a 3-prong plug.

I have never seen a 4 prong GM map sensor.

86 Camaro V6 should be port fuel injected and it should have a MAF not a MAP sensor. The MAF should be between the airbox and the throttle body. The only thing I can think of that has 4 pins would be the IAC on the throttle body.
