Loss of power after 20 mins of driving

[delb0y]

HI folks

well managed to sort one thing on the car and another starts.. i thought it was to do with the injectors but checked those .. there was a leak on one of the pipes the seal was replaced however i still have loss of acceraration where the car isnt as quick at picking up speed. Normally ok when cold after 15 - 20 mins it starts. Im unable to get the car on the star until after newyear now.
maf has been checked and is clean disconnected it but had the same problem
any advice would be appreciated

So it is a CDI

Do you find the auto box is a little hesitant as well?

Check the intercooler pipes for splits.
