Galaxy Diesel Jerking Acceleration

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!
