Sputtering at 2000rpm

[cdrive]

Hi guys. I'm hoping I could get some advice regarding my 2006 4.4L. It recently started sputtering in every gear when I'm at ~2000 rpms.

Service history
-new plugs two years ago,
-cleaned the rails 18 months ago
-cleaned the MAF recently.
-NO CODES

Any ideas?

Thanks in advance,

Charlie

First thing I would try is a throttle body cleaning.

No sputtering below 2000?

Thanks for your reply!
It doesn't sputter at any other RPMs (higher or lower). I did the Throttle body cleaning less than two years ago. Could that buildup reoccur so fast?
