Having problems with your GMC Jimmy ?
EVERY TIME I ASK A PART STORE FOR AN E.M.C. COMPUTER FOR MY 1999 GMC JIMMY THEY WANT TO GIVE ME AN ECM, OR A MAP SENSOR, SO...MAY I ASK, WHAT DOES E.M.C. STAND FOR AND WHAT DOES IT DO?
EMC, no that should be a PCM (Powertrain Control Module), that is what you need,there is no EMC computer on this truck you have your terminology wrong, the PCM controls all engine functions as wellas the Emission control system.
