| Smoke
Had the same thing on mine. I work road construction and idle around the job 10-12 hrs a day. Noticed blue smoke while doing so and really smoked a lot when I hit the highway at cruise. The dealer checked it, said the fuel setting was rich causing unburned fuel to accumulate in the catalytic converter. When adding power to accelerate to highway speed the converter heated up and burned off the raw fuel causing a lot of smoke. The dealer upgraded the setting in the injection system and eliminated it completely. Hope this helps. |
