1600-1750rpm Shudder/Rough Run
A question for you guys. Today I got home and for no particular reason ran the RPMs up to about 1600-1750 and notice the the truck ran real rough, kind of a shudder. After 1700 it cleared right up. Now in the past, since I got the truck I've noticed that in 1st gear moving along about the same RPM I get the same symptoms. Any thoughts????

poor running
Sounds like they haven't changed or improved the PDC and harness. MY guess is that it is a voltage spike corrupting the voltages from the vp-44. If you have access to a Fluke meter put it on frequency (HZ) I have seen HZ from 22 to 102. This is the problem.

bad harness
Will have to find out where the harness is attached to rest of the wiring and do (REDO) cryslurrss typical poor quality work. Have had to do a lot on this 99junk so am not happy with it at all.
Does anyone know where the splices are from the PDC.???
