Spark plug location 1991 buick riviera


can't clean spark plugs...and DO NOT buy Champion brand, use Autolite or Delco. Your plugs are accessible through the inner fenderwells...remove front wheels to get to them.
P.S. do yourself a favor and do this as well, or in advance of the plugs...go to Advance Auto and buy "SeaFoam" gas additive and follow directions...drive at least 100 miles.
Good Luck
