Quick Question...

"SHOULD" 30 minutes of driving on brand new spark plugs discolor them slightly??

They are currently whiter then my car and I don't know if it's because they are new :shrug: or because I'm running to lean??

I know they only get a light brown/pink tint, but this could help my diagnose a problem...

Also, if the car has been sitting a week would that cause the plugs to loose the discoloration??

Thanx in advance,
Jason
