i disconnected the battery and the light went out, the thing is, i had a slight misfire, it was occasional, i did a tuneup with all dealer parts, still had a misfire so i took it to a shop and they said injector misfire, when i put injector cleaner in it it went away,so....i bought some injectoer (rebuilt) and had em put in, it ran fine for about 500 miles, then i decided to take the car up to 100 mph to give it a test and it started misfiring again...since the light would not go out after disconnecting the efi fuse i thought something was wrong with the ecu....i guess i was wrong, maybe i have a faulty injector, should have bought new ones from the dealer but they are too expensive, o and btw when i put injector cleaner in it runs fine, no misfire at idle
