    I have a code for my explorer, map and baro showing high input, I bet that thing is stuck open. Autozone sold me the wrong part, just a map sensor, the map is part of the egr in mine, built together. Unfortunately things are tight and I cant get another until payday. I wonder if I can clean the damn thing ans if its even worth it. Just wait until friday and save myself the headache
