I HAVE 2006 PILOT 3.5L ENGINE THE REAR CAM WENT OUT FROZE IN HEAD .SO I REPLACED BOTH HEADS/ SPARK PLUGS TESTED COILS AND REPLACED INJECTORS BUT I
HAVE MISFIRE ON CYL # 2 ONLY AT IDLE. ANY IDEAS PLEASE HELP.>>>>>>

 

If you have just cylinder #2 misfiring,the problem could be the #2 coil. I would recommending swapping the #2 coil with the #1 coil to see if perhaps the misfire goes away on the #2 cylinder and then shows up in the #1 cylinder. If it does, then the problem is in the original #2 coil. If after the swap the cylinder #2 continues to misfire, then the issue is not in the #2 coil, but something else.

Hope this helps! At least it will help you to determine if the problem is related to the #2 coil or not.
