[Hernandez]

it is a 2002 v6 with almost 89k, im a getting a very bad mpg i think, 14.15 mpg or so. i add like 5.3 gallons each time i reload fuel and i get around 75 miles. i have had changed the oil every 3 or 4 months and i changed the sparks plugs and coils once. never changed the air filter lol what should i do to improve my mpg



and another thing i want to install a start engine button in the right side of the shift knob in the console , any ideas or photos? or what should i do to upgrade my ls

Well first.. REPLACE the air filter...

For the start button, your going to have to tap the lines going to the ignition.. You still have to have the key in and turned to the run position for it to start..
