Rough Low RPM Acceleration
 

Got a problem. The car runs, idles, and accelerates perfectly fine except between about 1000 to 1500 rpms. From experience it sounds like its misfiring -- rough, heavy, and jittery. Its not showing any CELs and I just recently replaced the ignition coils a few months ago. It doesn't make sense that it would only happen between those certain rpms. Just looking for any insight or knowledge (and yes, I've already searched.)

Thanks,
Nick

Check MAF sensor, plugs maybe motor mount too... sorry not much help

Yea, I've already checked the MAF, no luck though.
