I am throwing codes p0108, p0130,p0112, cylinder misfires, and and all kinds of other horrible siznat.. Will my car throw these codes if the MAP sensor is bad?? I am getting 14 MPG on the highway, stumbling, hesitation, and back fires.. I toook my car in and had it looked at, but I have a voltage clamp, and they said that they were gettinf funny readings, and couldn't tell what was wrong,....... they said possibly a bad MAP sensor? what do you guys think?
