2000 7.3 PSD Excursion Cold Problem

[Mike_42]

Does this when cold, I let warm up for 5 minutes before this happened as its been doing it. Going to plug in tonight, was about 40-50 degrees out. (Mississippi)

What do you guys think is causing this? Injectors? After I get off my dirt road to street it runs fine, also notice the turbo waste gate? Seems to do it most when reversing.

Thanks, Mike

Towards the end sounded like the ebpv closing. Which is normal.

Do you have a scan tool or torque? I would watch icp and ipr Duty cycle when it shudders like that.

What is a torque?

This morning it didnt shutter but the epbv was closing and opening making that noise going down the road at 40, once I got to interstate it stopped opening and closing.

What do you think is causing the shutter?

I'm not 100%, but I would think the trans. Is a automatic, right?
It could be trying to lock the convertor.
I wish Mark k was a member here. He knows these trans really well.
Torque is a diagnostic app for your phone. Uses a Bluetooth adapter that plugs in to the OBD II port. Or if you have autoenginuity.

Where can I buy the adapter for the bluetooth? How advanced is it?

The one I like is the obdlink mx.

Fairly easy to setup and use. Gives lots of information though.
