I have this 2010 fusion se I've had for 4 years now its been a great car until 6 months ago when i changed oil. it had a lot of oil in cylinders 1&2. after changing plugs. It had a hard start with oil in the cylinders. my question is would that have caused a valve to go bad. The check engine light randomly flashes every few miles causing it to loose all power pull codes of random misfire and misfire on 1&2. I have since then changed the coils. plugs again, valve cover gaskets, injectors, ecm, map sensor, mass sensor, throttle body. probably more I'm forgetting. I'm not sure where to go from here with car any suggestions
