ENGINE MISFIRE + KNOCK

Mercury Mystique

There has been nothing wrong with my car for quite some time it was recently seviced and I perform regular maintance and then the other day it misfired, the check engine light started to blink and I pulled over and turned off the engine. When I turned it back on, the light remains on but the engine didnt misfire. Now the engine has a slight knock and there is a lingerin smell of unburnt gas. What could be the problem?
