my dashlights and gauges have a mind of their own. the wipers go slow even on hi and the heater fan does not run at proper speed either. have tried other computers in the car and it won't start. it will start with origintal computer hooked up. all the gauges quit and sometimes the car too. then they will come back on a couple seconds later. no codes come up on dash. it does have command start but i do not have the remote. heradlights also flicker off and on with the dash lights as well. does anyone have any idea? i think it is a bad ground
