Spark Plugs and headlight allignment

Miles: 146665

Spark plugs replaced: Had cylinder 3 misfiring when engine was under heavy load. Its been a while since I had done sparkplugs so figured that was the issue. So far everything looks good.
000771 – Cylinder 3 P0303 – 001 – Misfire Detected – Intermittent

Drivers side headlight was aimed too low so adjusted it to match the passenger side.
