So got a CEL this morn. It drove like normal. When I got home. Turned the ign of,f key out. When I opened door sounded engine was running, but rough/misfiring. I was like wth. Put key back in ignition. Turned to on and it ran fine. Turned off. Same deal. It only did it for like 5-7 sec then finally died.
Anyone have this happen to them after they shut off their ride? Weird!


This is what my reader came up with.

 

My 1971 Demon 340 would do that and it is because of a hot spot igniting the left over fuel in the combustion chamber. It is called dieseling on old carbureted engines.

 

Same issue started the other day. Frustrating as I paid $650 to get this resolved back 4 mo ago. They said it was a junction block. My Dango is possessed. Not only does it keep running after I pull key out, but it has turned the lights on on it's own past 2 days. I think it could be PCM. When I took it to stealer ship. It pulled so many error codes. Anybody have this happen?
