Galaxy Diesel Jerking Acceleration

I own a 2009 Ford Galaxy with a diesel engine and 153226 km on the clock. Recently, I've experienced jerking during acceleration, the check engine light is on, and the engine sometimes stalls at idle. Error codes are stored, engine power is reduced, the engine runs rough, and there's a strong exhaust smell. Could this be related to the intake manifold?

Those symptoms sound awfully familiar. I had a similar experience with my Galaxy – felt like driving through molasses at times. Have you checked the manifold pressure sensor? A faulty reading there can throw everything off, much like a bad barometer messing up a weather forecast.

Thank you for your response. I have not checked the manifold pressure sensor specifically. Could a leak in the intake manifold itself cause similar issues, perhaps due to scorching? Is that what you experienced?

Yes, a leak in the intake manifold can definitely cause those symptoms. It's like trying to run an engine with a punctured lung. Given the age and mileage, scorching is a likely culprit. I'd advise getting it checked at a workshop; a faulty manifold can seriously impact engine performance and potentially cause further damage. That's what I ended up doing.

I appreciate the advice. I will take it to a workshop for a thorough inspection. It sounds like the intake manifold is indeed the most probable cause. The workshop confirmed a defective intake manifold due to scorching. The repair cost was 1180€. Thank you again!
