Hy guys sorry for my english im write from Poland.
So ive got a C4 2006 1.6 16v.
My problem is when the engine is on 3000rpm i fell like a power loss.
Im change the throttle, oxygene sensor, spark plugs, ignition coil.
After performing the ECU adaptation via diagbox, the problem disappears for 150 km and returns, There are no errors in the engine controller, The higher the outside temperature and the engine load (air conditioning), the more the problem increases, It looks as if the engine controller is incorrectly preparing the fuel mixture.
Can anybody help me ?

Re: Engine power loss
The best thing to do is have a Diagnostic scan with Diagbox and see what fault codes are stored.

Re: Engine power loss
What are you using to run a diagnostic test?
