| Post subject: | CRD Problem at 80-100kms when driving |
This is a hard one to explane in text. I have had my CRD for a year now and 6 months ago I noticed a problem while driving. Every now and again while driving between 80 and 100 kms the jeep will give a bucking almost like a bang ( hard to describe) like it looses it fuel for a split second some times two or three times in a row. When it happens I step on the peddle and it will drive out of it. The jeep works great and I get great fuel mileage, and I dont have any problems. Does any one have this problem? Does any one know what causing it? |

The EGR is starting to plug up and the intake throttle is choking the engine a bit. This can lead to light load misfire. |

When I had the timing belt and waterpump changed we cleaned the ERG and disconnected the map sensor. Cant be building up with soot |

Mine does this and I have seen others that have complained about it. Mine acts like a skip or miss fire, only does it while almost coasting, maintaining speed while going down hill. Step on the gas and its gone! Others have cured it with a tuning chip but they are 4 to 6 hundred bucks. |

Mine did this until I decided to clean and free up the turbo. Possibly not enough boost just off idle? |
