Engine sound seems normal, but now that you mention it, acceleration feels a bit sluggish. What was the issue in your case?

Sounds like the same problem. It turned out to be a faulty camshaft solenoid valve. If you want to be sure, you should get it checked out at a workshop.

Thanks for the help. Took it to the workshop, and you were spot on – faulty inlet camshaft solenoid valve. Repair cost 250€. Replaced it, and everything's back to normal now.

I had something similar happen with my Allion. Also, a check engine light and the fuel consumption went up. Did you notice any difference in the engine sound or feel any low power?
