engine severely misfiring, multiple fault codes, engine ran in limp mode. primary cause a failed, likely stretched, timing chain, one of the ones at the top of the engine, for one of the cylinder heads valve train. fixed most of misfire. secondary cause of misfire was severe carbon buildup in cylinder heads. cleaning the carbon build up fixed the last of the misfire codes, and the recommendation was to use the BG 44K every 6 months to keep it under control.
