Few questions on tune up parts for increased MPG (the truck has 194K) I'm getting roughly 10.4 (according to my DIC) in town. I haven't checked highway milage yet. I'll be installing a new cap and rotor later this week and i'm thinking about an MSD coil. Plugs are newish (5k miles) and wires are good. Alignment will be done monday as well and tires are new with good pressure. What other repairs are common for returning at least some of the mileage to this old motor

The first things for my stock truck I did was change the ypipe Catylitic to a new exact fit from jegs and I sprayed my O2 intake clean, and new oem engine pullys, they bearings go bad and drag
my tahoe went from 314 miles out of a 26 gal tank to 360 miles for normal driving. it's amazing. All that other stuff was just throwing money away.
You want to ease the engine function. Also a really old AC pump will eat your MPG too. All in I think I spent $720.00
