CEL 1997 ZJ 4.0
« on: June 18, 2015, 06:56:30 pm »
Had a CEL come on on my '97 ZJ 4.0 - any way to read this without an OBD2 computer hookup?  Funny thing is - CEL came on - performance and mileage improved (from 18.9 to 19.6!) - not sure if I want to "Fix" what's wrong or just put some tape over the CEL!

Cheers
