Be specific what engine? what vehicle? I know of no knob on a stock 1980 chev is it stock?.......
Perhaps: Bad fuel (water in fuel or tank) Timing out of adjustment--Worn timing chain (stretched) or gears? Bad distributer?
where are the timing gear marks on a 1997 chev s10 2.2 located
the ignition model in the distributer is bad, could also have a bad condensor at the distributer but doubtful, the model is a little black box located in the distributer
