lim, lower intake manifold. its under the upper intake the top most part of the engine under the cover. theres a loop of vac lines that can break.

why its best to have the code, map can have at least 2 different codes, each lead you in a different direction for its repair.

the map is the one that has the plastic vac line to it, the baro looks just like it, hells its the same part # even, but only the one with the vac line to it is the map sensor.
