shuddering at 2000 rpms

[xbrandonleighx]

new here! forum looks great!

im having a issue with my 95 7.3 shuddering around 2000 rpms. there is also a rattling sound coming from the engine aswell at the peak of 1st, sound is mild through 2nd then really pronounced in 3rd. i have a feeling that this rattle sound is coming from whatever maybe causing the shuddering.

no dash lights come on and the tach does not drop when this happens. no cab lights dim, nothing. just a straight up bone jarring shudder. it did it before i installed my bullydog 6 position chip very seldom...and now that ive put the chip and have been "playin around" with it, the shudder is worse and now i have a rattle.

i had the truck scanned and tested today at a diesel shop and got nothin. tried to show the guy what is does in park and i guess it will only do this stuff when its moving. it passed the buzz test but im thinking that i still might have a bad injector thats causeing this rattle? but would it cause the stalls if it wasnt working?

heres a video i took, you can really hear the shudder in this, not so much the rattle. pleae help! this truck still has temp tags and is my daily driver!

I'd look for a problem with the clutch or torque converter bolts as appropriate, loose transmission/bellhousing bolts, bad u-joints.
If it doesn't make the noise in park or neutral, it likely isn't any of the front drive accessories. Try maybe loose motor mounts or bolts?
Did you do anything, have any work done before it started making this noise?
