Idle Issue

Hi.
I am looking to purchase my first powerstroke and need some help. I found the exact color combo and option list that I want on a 2007 truck with 176,000 miles. I would love to buy it but right off the bat something was up with the idle. I am looking to find out why the idle is off beat because if it is a relatively easy fix ill have the dealer fix it for me and hopefully end up with a great truck.
Here is what happened yesterday;
super cold start at approx 25 degrees
immediately started but the idle was jumpy almost like the timing was off
I drove down the avenue for a solid ten minutes (one big pull) and once it warmed up the idle chilled out and the exhaust smoke returned to normal.
Today I went back to see if it would do it again on a cold start. And it did. However I didn't drive it today but i did take some videos.

I took two videos for yall to look over.



I watched almost every video on powerstrokehelp.com and the truck seems to have the symptoms of one or more bad injectors.
Does anybody have any ideas, suggestions, or advice?

Thanks much!

First of all DO NOT LISTEN TO BILL HUIT AT POWERSTROKEHELP.COM HE IS A MORON!!

Second sounds like some serious stiction in the injectors. I would ask them to replace the injectors and then buy it. Also get a monitor and hook it up and monitor the vitals such as FICM voltage, ICP V, IPR %, VGT %, EOT, ECT, Trans Temp, etc.

Also take the truck out on a decent grade at 50-60 mph and give it just a little throttle to keep the speed your traveling going up the grade with the converter locked. If it bucks/hesitates/jerks it needs new injectors.

Sounds like injectors to me. You need a monitor like an Edge CS or CTS to monitor engine vitals. Like Tuscany said, get it on a slope where you can provide constant throttle pressure and if it bucks or jerks it's your inejctors.

Great thanks for the quick reply. Ill have it checked out and update this with the results.

With a potential injector problem do you think this truck is going to have further issues down the road that i should watch for? Should the truck be driven with bad injectors? Is there anything i can to to prevent future problems? I plan on egr delete, 4 inch turbo back, and tune. Anything else?

Also if anybody can suggest a trustworthy mechanic in Idaho let me know.

Thank you.
