I have a 1988 Chevy c-1500 Silverado. I have installed new plugs, wires, D-cap, rotor button, Throttle Position Sensor, EGR Vaccuum Solenoid, check for vaccuum leaks (found none) and many other things yet my truck still idles very rough and so low that it almost dies when u come to a stop sign. WHAT COULD THIS BE?? EGR VALVE? Alternator? ECM?? It did have a very cool thermostat in it so i changed it due to the cold weather now my gauge reads very high even though the truck isnt that hot. Could someone have installed a Chip and that be why it had such a low thermostat?? Also once its warmed up and you come to a stop the volt gauge drops down to around 8 and if your running the heater fan headlights and anything else it really does want to die.......Help please.....any suggestions?????
