Suspiciouse of a negligent oil change service, since no warning indicators were displayed prior to service. Service performed due to time between services. Technition diagnoses was to replace coil 6. Coil 6 replaced and as I drove off, the car began with the same physical problems as before ans before I could make it back after turning back for the dealership the service engine light deplaned. Following day received call that another part of the same coil needed to be replaced. They kept car to make sure it was resolved. What's wrong with my car and why can't they competently explain the issue. Is it likely they made an error during the oil chang that is affecting my engine in general or coil pack specifically? If they rep Ace one coil is it recommended to replace the coil pack? M3Hawk

Did you ever find out what was the problem? I am facing the same situation ever since they changed the oil. My car starts shaking when it is going to turn off and it starts making a loud squeaking noise. I have changed already 3 sensors and they still don't know what it is. One of the mechanic told me to get a new engine. I just bought that car 10 months ago.
