2005 Chevy Silverado. Engine runs good. Willing to sell cheap and hopefully quick. I blew a tire the other day. The spare is a good tire. The other 3 are still decent. Got the blown tire in the box with the main wheel rim. The check engine light is on. I have a scanner and it is the Knock Sensor. Its been on for several years. No knocking. Not expensive to fix, but also not debilitating. An air bag service warning on as well. Shouldnt be expensive to fix but that either. I just couldnt justify it. Recently replaced the spark plug wires after a misfire issue. Fixed that problem. KBB is around $4000-6000.
