2002 2.3L studdering/bucking

[T1m3_Sh1ft3r]

Hello all,

well i have an interesting question for y'all, i have a 2002 2.3L with a hair over 84K on the clock, with a 5 speed, and it has a tenancy of bucking/studding at about 1700 to 2200 RPM with me barely on the throttle (about 10 to 20 %) doesn't matter what gear or speed. its been doing this for about 2 months and Ive had just about enough of it lol, I've tried replacing the plugs, put a can of seafoam in the tank and gone through the tank of gas. i replaced the fuel filter about 5 months ago so i wouldn't think it would be that. to does when i go out of my driveway, in 1st it will move just not very fast, then it will catch up. im thinking that the clutch is going out, but im not 100% sure

If it helps ive had the truck since 3K miles, and i learned to drive stick in it(since 2005), and the last 4 or 5 months the truck has been used exceptionally hard, towed my dads 1969 nova 25 miles, and towed my 1986 Trans Am 60 miles combination of rush hour I-5 traffic and highway speeds, pulling fiancee's jeep out of a ditch, and lots of heavy wood loads

Anyways any help is greatly appreciated, and if posted in the wrong section i do apologize

Disconnect the vacuum line to the EGR valve and drive it like that for a day.

If that cures the stuttering, replace the DPFE, reconnect the vacuum line and clear the computer memory by disconnecting the battery and turning the headlights on, then off, reconnect. Let it relearn the idle by idling for 5 min in each of these conditions:

Parking brake set
in neutral (5 min)
In neutral with AC on (5 more min).

well that does help a bit, not it only does it when i stay at a steady speed between 1700 and 2K RPM, if i keep that speed for more than .5 mile

Forgot to mention plug that open line (vacuum leak when EGR commanded open).
