I was wondering if it was normal that my crd is puffing black when cold and under hard acceleration. It doesn`t seem to burn any oil but fuel consumption is a bit high. Could it be the map sensor. Thanks. |

Do you still have the EGR valve functioning? Mine did that until I unplugged the MAF sensor, disabling the EGR - what is known on this forum as the "ORM", or Off Road Mod. Also, are we talking about a pouf of black smoke, or enough to make people in houses nearby call the fire department? |

Just a puff of black smoke. The engine is still stock, everything is still connected. |

Make sure your air filter is clean and your map sensor is clean. You should check the map sensor every 6k miles or so. I would be willing to bet your MAP sensor is dirty, when was the last time you cleaned it? |

Here is a link to the thread about pulling and cleaning the MAP sensor. Make sure if you use brake parts cleaner on it, that it is chlorine-free. http://www.lostjeeps.com/forum/phpBB3/vie ... hp?t=22630 Use a 4mm hex-head to unscrew it. |
