My 94 sse seems to be getting poor gas mileage. Should i use drive or overdrive. Is there anything to increase gas mileage?

What'* 'poor' and what type of driving do you do?

When was your last full tuneup?

Freeway? Use OD. City? Leave it in OD. The PCM and trans are usually smarter than us. They know what to do.

there'* a whole bunch of different things/ combination of things that could cause bad gas mileage... what i do is i click the search button at the top right, just search for "gas mileage" or "bad gas mileage." there'* SO much information from other people with the same problem (like me)

Right!

mpg is another good search phrase.
