i have a 96 coupe, and my check engine light comes on when i go over 65mph. i took off the battery cable and the check engine went away.. then when i hit the freeway, the check engine light cones back on? i comes on when i hit about 65 to 70 mph... any ideas??

 

did you check the code when you stopped or got home to see what it was?

 

The battery being unhooked will shut the light off till it reads it again..get a code and go from there Miles on car?

 

Check the code, it could be anything

 

Does the car react differently with the light on?

 

Check it:
