5.2L engine "bogs" ...here's the senerio, most noticable at 60+ mph, taching approx. 2000 rpm, lift off accelerator, and rpms drop to 1750 then engine bogs and rpms drop instantly to 1250 then rpms jump back to approx. 1700, and all is fine. This only appears to happen when rpms are decelerating and accelerator is lifted. Has anyone experienced this? Any help as to why? Thanks.

Check engine light on? Have you pulled the codes with a scanner?
I would start with bench cleaning the throttle body.

is it only with a sudden lift off throttle or every time regardless
There is no check engine light, and the only codes I see is 12 and 55 (nothing abnormal). I don't have a scanner to check other codes. As far as lifting off the throttle, it happens all the time, but appears more noticable at higher RPM's and speed. Above 2000 RPMS and 60+MPH, as RPMS drop to about 1750, it immediatly drops to about 1250 then back up to about 1700 RPMS. It may be happening at lower speed/gearing, but I haven't noticed it.
