Guys, I did a quick search and couldn't really find anything. When I first start my car there is a tremendous amount of whitish smoke that comes out the tail pipes. I just recently had my oil change and it made no difference in the amount of smoke. The only thing that my car currently does is run a little after I shut off the car. I think it has something to do with a shut off sensor? If I fix this will my smoke problem go away? Thanks in advance. Paul
