[DML] Re: Engine runs rough after pop & smoke from engine bay

Thank you soooo much. The problem has been fixed. Apparently what 
happened was the engine backfired and the pressure pushed one of the 
fuel injectors out of the boot. I pushed the injector back in and 
secured the retaining clip and the rough idle completly went away. 
On a side note what would have caused the backfire in the first 
place? This is the first time it has ever backfired, I recently 
leaned the fuel adjustment because the engine started to surge at 
idle, but i only leaned it a very tiny amount. Once again thank you 
so much.
