My car is feeling underpowered and is suffering from poor gas milage. How often should I give it a tune up? I just gave it one last summer, which was less than 15,000 miles ago. Is it time for another one? Why else would I be suffering from poor gas milage and being underpowered? Could my engine be coming to its end? ![[Frown]](frown.gif)

If your last tune-up was less than 15k miles ago then you should be fine, depending on what it is you call a tune-up. My tune-up means changing the plugs, wires, cap, rotor, fuel filter and oil all at once.
It can also vary on if your car is running on 91 octane (much, much better) or regular unleaded. If you have a K&N, maybe you should recharge it. If your car is stock, replace the air filter.
It might even be that you need to run some concentrated FUEL INJECTOR cleaner through your tank, you should of been doing that every time you have an oil change.

It was a complete tune up, and I always run 91 octane. I'll try the fuel injector cleaner, thanks.
