MIL light comes up yesterday (Tuesday) after my wife filled up the full tank with '89 aki gas. The car is '96 w/ 90k miles, regular maintenance, putting premium gas at all the time. Browsed the FAQ and threads down to May '03, can't figure out. Any suggestion ? Should I just wait till this tank of gas finished ?


(side note The day before MIL came, I did changed the entire set of Spark Plugs, every procedure (screws, connectors, etc) was followed (except that I wouldn't find the gap gauge so I didn't check the gap). It's the NGK BKR5E-11 VP Cu. Thought that the factory has pre-gapped at .044" already, shouldn't be a concern. Fired up and test-drove for 2 times around the area for 5 min, not found MIL that time.


Thanks for advice.

 

Have you pulled the code from the ECU?

 

Look the stickies in the 4th gen fourm and follow the directions on how to pull codes for the CEL.
