MAP question

[7.3psd97444]

Recently noticed my truck has been extremely doggy. Just slower then normal. Had recently replaced my ICP after getting 2 bad injector codes on the auto ennginuity laptop test. Put the laptop back up to it and the injectors and ICP are fine. Just had to get a new ICP. But got a code for a bad MAP sensor showing a constant 14 psi even at idle. I had heard that if you get this code, then unplug the sensor, and the truck has more power that you got a bad MAP sensor. So I unplugged it and it had a great gain in power. Truck ran much better. So today I just replaced the sensor with a brand new one from Ford and its back to being slow again. As if I never unplugged or replaced the old one. Anyone got any ideas??

Manifold guage pressure should be about zero. Manifold absolute pressure would be about 14 depending on altitude.

Check the map connector wires and all the way back leading into the harness.

Ok maybe I was reading the absolute. But it still coded being bad.

Will do.
