C6 Jerking Acceleration Loss of Power

Sounds familiar. I had similar issues with my C6. The jerking and reduced power are dead giveaways. Have you checked the manifold pressure? If the ECU is throwing codes related to that, it's almost certainly the intake manifold. Is it more pronounced when the engine is cold?

I haven't specifically checked the manifold pressure, but I did see a code related to air intake. And yes, the symptoms do seem worse when the engine is cold. Is it possible that the intake manifold is the culprit?

Yep, sounds like the intake manifold to me. Scorching is a common problem. I'd bet that's where your leak is. I ended up biting the bullet and getting mine replaced. Cost me a pretty penny, but it sorted everything out. Honestly, I'd recommend taking it to a trusted workshop to get it properly diagnosed. They can pressure test the system and confirm the leak.

I appreciate your input! It's reassuring to hear that someone else has experienced the same issue and resolved it. I'll definitely take your advice and bring it to a workshop for a proper diagnosis and repair. The estimated cost is around 1180€. Fingers crossed that replacing the intake manifold will solve the problem!
