Hi all,
Firstly its good to be back!!
I have a 1.8 2003 Elegance and it seems to lose power when I hit the 4000 rpm mark. It used to do this in 3rd,4th and 5th but 3rd seems to have cleared slightly. When I do push it past 4k in 4th I see a not too pleasant cloud behind the car momentarily.
It has had a service, just waiting for full coolant service to be done - speak soon Caveman. I have been told to steer clear of products like Redex, etc but I am thinking it is a carbon build up as I believe the car was stood for about 18 months before I acquired it.
Any help would be appreciated.

Cheers
