My girlfriends dart is well a special car. Definitely understand why yhebdart got a bad rap with hers. The thing is always broken. That being said her car will randomly smoke from the exhaust when left to idle for a few minutes . She took me to the pharmacy a couple weeks ago and me inside for about 10 mins her in the car with it running started to smoke. Once it does this reving it up creates more smoke. It doesn't go away until it's been shut off for a few minutes and then once restarted it's fine. It does smoke a lot if you rev it up while it's smoking it will smoke as much as doing a seafoam treatment. It's quite a bit. Also when taking off from a standstill you'll hear the motor cackle like a spark knock on initial throttle input. The dealer ship of course cannot find a thing wrong. So all suggestions or thoughts are appreciated. No cel or anything either.
