Default Problem with Spark Plugs / Idling / Coils =\

Hey, I am new here and would appreciate the experts advice about some problems with my Bonnie.

I recently started to have extreme stuttering when accelerating or idling. So, I replaced the spark plugs with some NGK V-Power TR55 gapped to .060 and changed out the spark plug wires as well.

That did not seem to remedy the problem at all. So I checked out the Coil Packs and one of them seemed to give a different reading with my ohmeter than the rest. I replaced that one and now my car will barely start.

I checked the spark plugs after this happened and they seem to be a yellowish color on the tip and have alot of carbon buildup on them. And possibley some oil on a few of them.

Any help or suggestions would be greatly appreciated.

Keep up the good work.
