My 99 Maxima shudders slightly when it idles in the drive gear. When I shift to neutral or park, it ceases to shudder. Not long ago the engine misfired and I had two coils replaced. I don't know if other coils have also gone bad or the O2 sensors are faulty. Any responses will be much appreciated.

 

i got the same problem i havent replaced any coil packs im now thinking that its a motor mount
