It could but it could be a loose gas cap. Stop by an auto parts store and have them read the codes.

Retired my 94 YJ 4cyl 5spd @ 200K
Now in a 04 TJ 4cyl 5spd CV @120K+
Both as a commuter vehicle in NW, NJ
April 2012.downsized and now a 99er.

What year TJ do you have? If it's any year but 99 to 00, the Jeep can generate is own diagnostic trouble codes by turning the ignition switch on-off-on three times within five seconds. Leave the key in the On position and wait, several seconds after the last on-off-on, any stored diagnostic codes will begin displaying in the odometer. Write them down as they display and tell us what they are. We'll give you the right list of codes to decode them with.
When you have a choice, buy American.
