car stalled when stopped with engine running. Smoke coming from engine on 2011 Mercedes-Benz E550

on E when stalled and added gas from a can...started up and ran fine. About 1 hour later went to drive again, went about 2 miles and clicking sound came from engine. Began to stall and when I pulled over it smelled like fireworks and smoke was coming from the engine. Turned car off and it stopped.

was the engine overheating,is there oil in the engine?sounds like you are going to need to check some basic things like compression.
