On today’s episode of DIY Willy we try to fix the 2011 5.3 Chevy Silverado. The ECU showed a check engine light code P0304 and was angry, The truck had a rough idle but ran ok. So in this video we will change the spark plugs and hopefully clear the misfire on #4 cylinder.

So follow along as we continue to repair and upgrade our 2011 Chevy Silverado.
