My sentra is at 68,000 miles. I was just wondering, how long do they usually go without being replaced. Also, can my timing bu adjusted by the gun or by computer. It feels like it needs adjusting. I also have tekwire wire set and NGK plugs. Do you guys think I should put NGK wires instead and my car would run smoother. Thankx in advance for your help!
