Driving almost every car on LPG I've got problems with iddle on NGK. 1 (2cv) or more cilinders (on a CX) diy suddely; only wide open throttle will bring them back alive, same with my turbo 2cv, then I tried Champion spark plugs and all my problems are gone, so for me only Champion..........

BTW. Champion is French isn't it, and what are our cars from,,,,,,,,,

ive always used 6's and never had a problem, ngk all the way

incidently does anyone use iridium plugs?

lpgo not had much success with champions in my outboards, but then again this is a 2cv forum not an evinrude omc forum..
