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

["deepdmc" <deepdmc12@xxxxxxxxxx>]

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.
