Hey guys, my 97 cabriolet has been having an idle issue for about a week, turned her on to go to work one day and she was sitting at about 1200rpm. going around the block, she would rev to 1200 when i hit the brakes. so that went away for about a week, and now when i come to a stop, hot or cold, put her in park, she dies instantly, rpm drop, lights come on. dead. any suggestions??? thanks
