Wierd: studder goes away speratically

thought I would start a different thread about this so I can keep it separate.

I have been chasing a studder issue for a while now.

Replaced:

- Injector o-rings
- #6 injector after a diagnosis
- all sensors that have been brought to my attention have been replaced
- new EGR valve, but after about 3 weeks the EGR code came back

heres the weird thing:

I had the studder every time I drove the truck, but the last 3 or 4 times I have drove it .... once the truck reaches EOT of 200 and I make a stop..... once I start back driving it smooths out. My last drive I went 10 miles with no studder at all.....even smooth at idle.

maybe someone can shed some light on this weird issue.

Thanks,
Dave

I'm having the same issue. My ICP is a little oil soaked though. New one on the way. Hoping thats my issue. Have you replaced the ICP?
