Hello everyone

i have been having and issue with my w220 s320 cdi.
When the engine is cold,the throttle engages 100% and the acceleration is great,as soon as the engine reaches operating temperature the car wont go above 2.5k rpm and will barely accelerate.
If anyone has had a similiar issue please let me know as ive been trying to fix it for a while but every mechanis seems to give a different solution so im not sure.
Thanks in advance
