Replacing All Spark Plugs
Call me crazy, but I just dropped off my car at the dealer to do some preventative maintenance. All these spark plug stories and getting stranded have me paranoid, so I decided to have all of my plugs replaced just to be safe.
The car has been running strong on the Renntech tune with the exception of a few sporadic "shudders" while idling. Cost is about $500 for replacement of all 8 plugs. Asked the dealer to return all of the old plugs so I can inspect and post pics in the forum to show what plugs on 3K miles of Renntech tune look like. Should have the car back later today.
