99 powerstroke f-350 dying on the highway???
Hello everyone, I would just like to thank everyone in advance for any advise or help they provide.
I am a noob with diesels and I just bought my first one a few weeks ago for towing purposes
The truck is a 99 f-350 with the 7.3 and manual trans. I bought the truck and it had no issues whatsoever but since I have a double car enclosed trailer I figured it would be a good idea to go ahead and have an intake, exaust and chip thrown on at my local diesel performance shop.
After I got it back from the shop I can't make it anymore than 20 miles on the highway before the egt's start dropping and eventually the truck shuts off completely. I took it back and had them update the chip, check the injectors, replace the fuel pump, replace the fpr, and still does the same exact thing and I don't want to keep wasting money throwing parts at the thing because it isn't helping. When the truck dies, if i let it sit for about 5 mins it fires up and drives just fine for a few minutes then proceeds to die again. Over a 20 mile stretch it dies anywhere between 1-5 times the exact same thing everytime. It starts as a slight hesitation but within 1-2 mins of the hesitation it dies completely with egt's around 200 degrees
To me it seems like the chip is what is messing with it because before it never had this issue. It is an edge evolution cs dash mount just so you know, and I want to see if this is a common problem for anyone else?
Again thanks in advance for any help and Ideas, my shop just has no idea whats up and I need my truck to run asap.
