Hesitation when accelerating?

[Deegle]

Hello All!

I have a 2015 Ecodiesel with 106k miles. It is stock but for a K&N cold air intake. I use hotshots fuel treatment regularly. Lately it has been hesitating under acceleration. If I floor it, the hesitation is very bad and the truck jerks violently. This is particularly pronounced when the vehicle is cold. Sometimes when I drive it though, it is fine and does not hesitate at all. Any ideas?

Thanks!

This is likely your problem, in addition You are hoping you Don't have warped Intake valves.

Thank you. Is it difficult to remove and clean?

Good idea. I just bought it from my dad a bit ago. I’ll check if he did it.

Hi gents,
Any updates on this hesitation issue. I find it more prominent in morning Start...I did replace fuel filter, and intake manifold. My manifold was really gunked up but I cleaned the runners and replaced manifold....still exhibiting same symptoms. No codes at all...I'm pointing towards fuel pressure. Any thoughts

Forgot to mention it's a 2015 with about 120xxx miles
