You may be carboned up which will give you hotspots in the chamber that can contribute to pinging or detonation. One thing I used to do on my Duster years ago was to fill up a beer bottle with water, put my thumb over the opening and let it slowly dribble out while the engine is running at 1500-2000 rpm. Would run 2-3 bottles through that way. The water helps to rid the engine of carbon deposits. You get the same benefit with water injection plus with the injection it lasts longer. The car companies used to make some cleaners to do the same job, petroleum based, but with those there is quite a bit of smoke coming out of the pipes. Not good if you have neighbors.
