So i rebuild the underneath of the truck (new trans, clutch, fly wheel, driveshaft, ujoints, rebuilt axles, leaf spring bushings, ball joints) the whole spiel. Now sense I've done that the truck starts up normal but has rough idle until i rev it at 2000 rpms or start driving and it goes away. I noticed that the bolt holding the wiring to the pcm is loose, could it be from that or from clogged fuel lines? bad sending unit? bad fuel pump?

 

What flywheel did you go with? SMF or DMF?

 

The flywheel is the one that came in a kit when i bought the clutch kit with flywheel from napa auto parts.

 

That doesnt tell me much. IIRC you can get it both ways from them

 

its just a solid flywheel and this is the link NAPA AUTO PARTS

 

A Dual mass Flywheel(stock) will dampen the pulses from a diesel engine. By putting in a SOLID flywheel, you now feel the pulses. Just get used to it
