i had a new accel supercoil on my mustang ,it ran but just didnt seem to run right,i pulled a plug and checked i had a yellow spark ,i contacted accels tech department they said thats perfectly normal,which also took about a week to get an answer from,so i contacted msd got an answer within 24 hours,so i bought an msd blaster coil,nice blue spark runs fine now,its pretty bad when a company has to lie to there customers to cover for there junk products,i think i will stick with msd they seem like a pretty decent company to deal with ,just thought i would pass this along ,so accel doesn screw you guys like they did me
