You should take the car to an autoparts store and have them use a scan tool to retrieve the fault code(s) that are stored in the car's computer. Most parts stores will do this at no charge. That will give you an idea of issues with the car. Excessive fuel consumption can be caused by a timing issue, a compression issue, or a fault or leak in the fuel system. Getting the fault codes would be a good place to start in identifying potential causes. Hope this helps and best wishes.
Plugs are a definite possiblitity. Since you just got the car, I would look at routine maintenance items first. New plugs, check condition of plug wires, check condition of battery and wires, new air filter element, new fuel filter, change oil and oil filter, new pcv valve, check cap and rotor, etc. These are things I do when I purchase a used vehicle. Most times you never know how well maintenance was kept up on a vehicle by the previous owner. I would start with the basics and go from there. If you have the equipment and facilities, I would perform a compression test on the cylinders and a fuel pressure test at the fuel rail.
These are things that I usually do. This is not really that expensive and I look at it as an investment that should pay dividends later on. Hope this helps and I wish you luck with your car.
