Truck runs very choppy

[rjbrock495]

Hey guys, looking for a point in the right direction. I have a 95 with a 5 speed. Sometimes, randomly when I push in the clutch and come to a stop the truck starts shimmying and running choppy. If I hit the pedal and bring it up to about 2000rpm and let off it goes away. The previous owner said that there is crack in the fly wheel? I have never heard of that happening. Has this happened to anybody else? Is it a cracked flywheel or could it be something else? Thanks. Any info would be much appreciated.

Could be a throttle position sensor, fuel pressure, injector control pressure, and maybe a flywheel but idk much about manuals.

Thanks, I'm going to start going through it this weekend. I check all of the above.

remove the inspection cover from underneath at the flywheel. have a look in there and check for movement of the flywheel while someone pushes on the clutch. grab it and see if it moves side to side. a lot of times a dual mass flywheel that is coming apart will produce misfire symptoms, clunks and noises like what you've described.
if you have a dual mass, that's probably what it is
