Anyone know about map sensors?
So I'm having some problems with rough idle, poor gas mileage, low power to accessories, and bucking and hard shifts. My steering wheel is also hard to turn. Sometimes it will be easy enough to turn with one finger on a hot day (but only for a few seconds) until it is hard once again.
So today I unplugged my map sensor, and pulled on the wire a bit to find where it went. Now all of a sudden everything is working better, and my car is running better. Does anyone know what that vacuum line is that connects to the map sensor? What does it do? I think the hose may have a hole in it, or its not securely on. My gauges light up brighter now, I have more horsepower, and my system hits harder.
It is still not 100% fixed, but what would cause this?
