I would like to know the exact function of a module in my car called a E.S.C. Electronic spark control. I know it isn't the ignition module in the distributer or the computer that controls the engine.I have a 1991 Caprice with a 5.0 and I have had bad ignition cutout when the car is warmed up. the entire ignition cuts in and out when the car is under any kind of load. I have replaced the cap, rotor, ignition module 4 times. Also I replaced the P.C.M. spark plug wires and plugs. and yet the problem persists. It is a open loop problem as the car doesnt miss a beat when its cold, it starts up great even in -0 temps but as soon as it reaches normal opp. temp the problem starts agan. it seems to happen when the engine needs to adjust timeing during acelaration. all other sensors check out good and there are no shorts or grounding problems.
