I have recently "inherited" a '94 G20 I have already replaced the valve cover gasket, the spark plug wires, spark plugs, starter, basically just minor stuff but I can't get the car to run right i get it started and it runs for a few minutes then after it warms up i guess it starts loosing power and the RPMs drop drastically (most of the time it stalls). Now neither of the radiator fans work and the car over heats does anyone have any ideas what could be the problem and how i should go about fixing it.....if you have more questions you need to ask to help me then feel free ask me and i will try to help answer them as best I can to get to a solution and get this car running again.
