Use of Techron
My '89 300TE was running rough at idle, just not the same old smooth self. Having been told by an independent Merc. shop that Techron works on cleaning injectors I though I would try a bottle with 3/4 tank of gas. It made all the difference, the old smooth idle is back and that's all I did. Food for thought.
