Just intalled a D7157 on my o4 not 4.5 vin is a 4 it runs really rough when at idle cold or hot engine, if i put a little throttle to it the miss gos away, also in the 60hp setting while driving it jerks and misses aswell cant seem to make that go away as soon as you use the throttle it starts runs good on 90hp no problem lots of power. It did not throw any codes either please help

sounds like there may a problem with the harness.
Id look into having it replaced by the dealer you got it from, if not, fill out the rma request form on our site and we will take care of it.

I ordered it staight from u guys what do i have to do to get this problem fixed.

I just received my power puck (D7157), and my truck ('04 3500) is doing the same thing. Is there anything that can be done without having to send it back?

Check for corrosion on the terminals on the harnesses.

Ok. I will check them after while and let you know how it looks.

Checked everything and also changed the fuel filter, and still does not act right. What would be the next step in tryin to resolve this issue?

Any ideas? If I am going to spend the money to get something like this, I would at least like to be able to use it without having to worry bout messing my truck up.
