MHD Log (Help Me)
Hey guys, take a look at my log and please offer some insight on where I should be looking for my issues.
Log 1: https://datazap.me/u/candyhacks/log-...og=0&data=3-24 Log 2: https://datazap.me/u/candyhacks/log-...og=0&data=3-24 DME Codes: Several Misfires Combustion Misfires Cylinder 1, 3, 5 Mixture Control Oxygen Sensor before cat: dynamics Oxygen Sensor before cat : line fault Oxygen sensor before cat : temperature I've changed coils, sparks like 1000 kms ago. Valve cover was cracked and changed. OFHG changed as well all within 1000 kms ago. Cold start car starts normal, then rpm drop into a shaky rough vibration and white smoke comes out the exhaust with the exhaust sputtering. It eventually stops when engine is warmed up. Car also smells of fuel when under load. Based off the logs I see there's some issue in the Lambda afr bank 1 but I'm not sure. Please offer input as I don't know what to do now. Thank you. |

Just trying to get some insight on the logs. I kind of realize that it maybe injectors but I don't want to spend $1500 on index 12 to find out that wasn't the issue.
The car already has index 11 on it. Can anyone interpret something based off logs? |

The stumbling on start up with white smoke is the classic symptom of leaky injectors. The engine doesn't operate closed loop until the sensors are warmed up. So whatever is happening on cold start has nothing to do with the O2 sensors.
Pull the plugs before your next cold start up. If you see wet, black plugs, it's an injector problem. Your vehicle may have any number of problems but bad injectors is one of them. |
