does anyone know how to test the baro sensor for a 1986 camaro? i keep getting the same code saying that i have a bad ground no ground or faulty wiring for the baro sensor. how do i test it? and also is there supposed to be both a map and a baro sensor in the same car? does anyone have wiring diagrams for baro or map sensors? also when i go over 50 and start slowing down the engine light comes on and the car begins to become sluggish and drops speed rapidly without applying brake someone please help
