Recently had a check engine light blinking indicating that the engine was misfiring the engine was running rough during idle and jerky at speeds of 50-70mph. discovered that the ignition coil was not working for the 4th ignition wire. Changed the ignition coil and replaced the spark plugs. Now the check engine light is off and the car runs better at idle, but it is still jerky at speeds 50-70mph. Any suggestions what to look at next?
