You may have a second issue with the coil pack being faulty. Does it judder on acceleration and when trying to gain speed to go uphill. Does your ABS light come up on the dashboard when it judders?The car is now jerking when at a light. Never felt before and I honestly thought the car behind me taped the bumper and got out to look but they were not even near it. Happened again a few signal lights away. I have a brand new battery in it which I took back to pepboys to test and they shows me it good. And I also have problems accelerating and I'm scared to get on freeway if the on ramp isn't long enough to allow me enough momentum to merge on. I'm so fed up I think I have a lemon and will give Strategic Legal Practices a call because they got my parents didge journey to be bought back with a little over $50,000 back to them. Ugh so frustrating.
