Eml And Up In Smoke With A Bang

[snappy]

Hi all, I'm looking for some ideas about my new friend engine management light. I filled up at the services and was coming up to motorway speeds when I hear this huge backfire. I felt the car momentarily loose power and shudder. At this point I see the EML light flashing.

 

Slowing down I continued to drive on. The car is driveable on both petrol and LPG but I have now about 60% power and the engine sounds really lumpy and uneven almost like it's running on 3 sparks.

 

Does anyone reading this recognise the symptoms? I'm sure this fault is not too uncommon but I couldn't find anything quite like this looking back on here so your ideas would be useful. I'm thinking a sensor.

 

 

Thanks !!
