Q: Can bad plugs cause shuddering when accelerating?
I understand some of the Ford models form this year may be experiencing shuddering b/c of a factory defect that the company announced earlier. However, can bad plugs cause shuddering when pressing the gas pedal, especially on heavy traffic or going at a slow speed? The vehicle has 60K+ and I have never done a tune up, or changed to new plugs. Please advice.
My car has an automatic transmission.
