Weird Issue After EGR Delete & New Turbo

[bkdsm3428]

I have 2005 F250 6.0 Liter Diesel truck with a strange problem no one can seem to figure out. I just had my turbo go out and my EGR cooler was leaking, so I had the turbo replaced and did an EGR delete on the truck due the number of problems I have had with this EGR system. After getting it back from this work, I have this jolt/jerk happening about every 3-4 days when I am coasting up to a stop sign or stop light. Generally this happens at speeds of 20-25 MPH. It makes some kind of whining noise that sounds like it is coming from the left hand side and bottom of the engine and it will do this for about 4-6 seconds, and then the whole truck jerks for a brief second, makes a terrible sound (first time it happened I thought my engine fell out or something) and then the whining goes away and it does not do it again for another 3-4 days. I have had it in the shop 3 times now, it won't replicate with a mechanic looking at it, and they have ran the computer diagnostic on it and everything seems to be running perfecting, engine, transmission, ABS. Thoughts?

I read a post about some one whose truck, or neighbors, was surging like that. Don't remember if it made a sound with it but he mentioned it surged straight into the garage door. Sounds like a similar issue. Everyone thought he was nuts.. Its in here somewhere.

wonder if it's an accessory drive noise. maybe like a powersteering pump or A/C compressor locking up.

Not too sure about this one. Let us know what you figure out.

Yes, I think people are starting to think I am nuts too because only myself, my wife and son have heard/felt it. I will search for that other post because I am at a loss. If I figure it out I will definitely post in here.

searching "surging forward"

Most issues were resolved with an ICP sensor or icp harness.

The random-ness of it does sound electrical. Chaffed ICP harness grounding out from time to time?

The issue just stopped happening. It had seemed like it was not jerking as hard the more time that passed, then about 2 weeks ago it just stopped doing it all together. No idea, but I am going to get my camper out of storage on Friday so I hope it is ready for that!

Those are the worst kind of problems....the kind that simply go away.
