That's a good idea. I've always found working on peoples cars if everything seems in order but you get bad mpg, clean your injectors & change the filter.
also everyone should own a scanner if they do work on there car. Not to rad codes but to look at data scream and stuff like that. The good autozone scanners will allow you to look at most of the sensors in the car while the car is running to see if they are operating correctly. Your base timing might be off killing mpg. You can also look at short/long fuel trims to see how the car is doing. You can check to see if the car is switching between open/closed loop..........
