While idling in gear, I feel an occasional "bump" from my car. I know it's probably something to do with the ignition coils, but today I noticed it while in park and neutral. Dumb question, but does this mean the coils are getting worse? I plan to take it into the stealership in a couple days. (Yes, I know it's possible to do it myself, but this is my only option seeing as I have no mechanical know-how and I live in an apartment with no garage.) Hopefully they can fix it.

 

smathing happening here, rough running, light comes on p01320, but with no other code to let me know WHICH coil, and the mechanic has no way of telling which and says replacment would be $80 each!....wish I knew if this was an easy do it yourself job. Good luck to you...any help anyone?
