My 1990 Acrua Integra LS Check engine light is on and the S3 light blinks since I took out a fuse and put it back in where it was while the car was off. And it does not have the pick up as before . My buddy told me to unhook the battery and hook it back up but that did not work. Can any one tell me how to get it off and or how to fixs it or what I need to fixs it. but my wife is mad now. HELP!!!!
