Cummins Loping After Being Put In Gear On Cold Start Up?

[Thundershot5726]

So I’ve been having this issue lately where after a cold start or more a first start after the truck has been sitting for a while, I wait a few seconds to let it build oil pressure, then put it in the drive.

It starts to lope, but it goes away after a few seconds.

It’s been happening ever since I put in a new HRVP44.

At first, I thought it was because of the injector lines because they were leaking like crazy.

Still, I’ve put brand new ones in stock size; even the cross-over tubes are brand new.

I am unsure if this would be normal with my work, but I don’t want to take any chances.

I have a 2002 Dodge RAM 2500 quad cab long bed with 210k miles.

It’s got 85hp injectors, brand new stock size cross-over tubes, brand new injector lines from Scheid diesel stock size, a hotrod VP44 from Industrial Injection, a FASS lift pump, and a built trans and a Spoologic “stage 2” turbo.

It’s got a brand new camshaft sensor and a brand new apps from Napa oil changes are always kept up on, truck has zero codes
