I inherited this car. It hadn't been driven in 16 years. It was garaged. I replaced the Spark plugs, spark wires and check ignition coils and firing order. They are all fine! There are no engine codes. Yet acceleration is EXTREMELY poor and fuel mileage 5.4 MPH. There is a strong smell of unburned fuel at tail pipe. Please help me I am at wits end! David Sr.
