| Post subject: | ENGINE MANAGEMENT LIGHT |
Hi everyone can anyone help with this. I tried to start my 04 cherokee/liberty crd to quickly without allowing the glow plugs to work, after cranking over for a few seconds i turned off the ignition and tried to restart again this time allowing a few seconds for preheat, my jeep started but it was in a sort of limp mode with no throttle response and a lot of smoke. I turned off the ignition and restarted again, this time it ran fine but, the engine management light is now illuminated. I would appreciate any info on what may be the problem and also any info on how to turn off the light. Thanks, Duncan. |

The temporary limp mode probably triggered the check engine light. If the problem has gone away there is a really good chance the light will go out after several (any where from 3-10 or so) regular runs to operating temperature. Otherwise clearing the light will require a code reader. |

If I were a betting man, I would bet your EGR/FCV just failed. I would probably bet pretty hard too, lots of cash. |

It's an 04 export model with a different EGR and IIRC that EGR can be turned off by plugging a vacuum line with no CEL being thrown. However, I'm doing this from possibly faulty memory and will defer to an actual 04 owner. |
