Double check the tightness of the spark plugs. How new are the rest of the coils? I had a bad Bosch ignition coil on my N20 and it was causing rough idles and stutters through acceleration.
Also double check your chargepipe clamps and make sure everything is nice and tight. Any air leaks will cause the MAF sensor to tweak out.
