Engine Mechanical problem
1991 Chevy Camaro V8 Two Wheel Drive Automatic

where is the ecm and prom located on 91 camaro.

and how do i know if ecm may be bad. i was wondering becuase i could crank the car up and unplug the map sensor, the mass air flow sensor and idle air control sensor and i heard no changes in the engine. Before if i did this the engine would shut off immediatley. the engine runs bad anyway and i cant figure it out it idles very roughly. but will take the throttle and sound fine when i put my foot on the accelorator.
