I have a 1991cadillac coupe deville wit lack of power how do I fix it
I'd try a tune up first. New spark plugs, spark plug wires, distributor cap, and distributor rotor. New air filter and fuel filter wouldn't hurt as well. Replace the PCV valve and inspect the PCV hoses. Make sure they're clear and not damaged. Check and adjust, as needed, your ignition timing as well. HTH. -Jim
