Re: 91 vette (6spd)
first off hi and i am not sure i have ever heard of fms 21# injectors so this might not apply to you but are you wondering if white is a bad color for the insulator of the plug it all depends on how long the plug has been in the chamber for if you are looking for it to be a bit more tan in color then that is okay too heck even some plugs will be a bit on the reddish orange side with the different additives in gas and the location where you live these days in my experience most all sparkplugs i have looked at start off with a white insulator

Re: 91 vette (6spd)
Why do you think you have to check the plugs at every gas station?
The car is still stock or at least internally stock? If so, drive it and don't worry about it. Those plugs should last at least 20,000 miles under normal driving. If it gets hard to start then pull one out and see what it looks like.
As far as if you are racing the car then thats a whole new ballgame.
