Whats up, my check engine light turned on and my car was like when i had it on Drive or Reverse it would idle smooth but at times it would give me a lil shake and the rpm drops to like 650-600. then sometimes i accelerate the car slowly and at 1500-2500 rpm it shakes like its about to shut off. and when im on WOT on 3000-4000 rpm it like loses power then gains it right back after dat. so i took it to the shop and they said my front o2 sensors needed to be changed.i went to a nissan dealer and changed both of the front ones and the check engine light came off.but i still get the problem at idle sometimes. and like at 1500-2500 rpm it still does it but doesnt do the higher rpms. i was told it could be misfire on one of my plugs. PLEASE help me guys my first max and i really want to keep it.thanx

its either your spark plugs or ignition coils.
if its your ignition coils, the ecu will throw a code, as to which cylinder is misfiring.

otherwise one or some of your spark plugs can be fouled.

if its been awhile, its good to change them (not that expensive anyways)
