Besides THE obvious checking of the SPARKPLUGS & WIRES What Else
SIGNS Can I Look For To Decide If I need To Replace the ROTOR/DISTRIB CAP Is There Anything Else I Can check Out ??? On A 1993 300 E 2.6

 

examine the distributor cap at night and check for sparks around it . . . if u' see any spark around the cap then is cracked and need repacing.
