service engine light
 

just wondering what are thecommon troubles that might make the" service engine soon"light go on .i know it could be anything but sometimes you find someone who has had the same and could help.any advice helps me.thanks

bring it somewhere that has an scan tool so they can pull the codes

Once the codes are pulled you can fix the problem
Most of the common codes are posted here
this is if you have an 96+
