So, I had a crazy experience with my Focus the other day. It started bogging down when load was being put on the engine. There was a green liquid in the spark plug wells so my immediate thought was cracked head. Turned out to be degreaser from the car wash the other day. Vacuumed them or and changed the spark plugs just for good measure and is working great!
Side note: having some noticeable noise coming from the front passenger tire area. It's almost a knocking nose accompanied by a shake at highway speeds. Could it be an unbalanced wheel, bad alignment, warped rotor? How should I diagnose it?
