93 GA getting bad gas mileage

[sorrymrofficer]

My car usually gets very good gas mileage, but lately it's been around 10-15 mpg. Any ideas of what's going wrong??

Is the check engine light on? If it is get the code read and post it here. If not I would suggest changing the O2 sensor. They are usually the most frequent culprit of decreasing mileage.

You may also want to check for a fuel leak just to be certain you aren't leaking any gas.

It may also be time for a full tune up as well! When was the last time it was done?

I actually have no idea when the last tune up was done, I guess i'll do that...

and no there are not any check engine lights on.
