Hey Scotty, long time fan! I have a 2003 Nissan Altima with the 4 cylinder engine. She has 170,000 miles, and still runs like it only has 90,000 miles on the odometer. Sometimes when I cold start the car the noise is pretty aggressive. It runs just as fine as any normal start, but Is this anything to be concerned about?
