I have a 2010 C30 T5. When accelerating it loses power. It will take off with its usual gusto and then lose power. The car still accelerates, but more slowly. Usually it is a pretty subtle event, but sometimes it is more pronounced and the nose will dip. It seems to happen less before the engine warms up, but I am not sure of that. Has anyone else experienced this and what was the fix?

 

I have the exact same problem, at 3200rpm there's a drop in power all the way to the redline. Have you found a solution?

 

Have you check the codes ? but this is quite common due to the fuel pressure regulator but the OP post is very old now

 

there are no code when i plug it and fuel pressure is stable when i floor it, according to the obd2 scanner. It's been like that since I bought the car 2 years ago and it doesn't matter regular or premium gasoline it changes nothing. At this point I'm just looking for as much information as I can get.
