car not picking up speed as it should sometimes
 

s500

The car is not picking up speed..its going up to 30ish max and sounds like its revving up:confused: ... unless, I start the car, leave it on for 2 minutes and then drive it..it drives normal..

But if the car was off over night and I get up in morning to drive right away, it takes like 40-60 seconds for it to go full speed (regular speed how it should go right away)

Basically, when I press the gas pedal, it goes very slow until about 1 min of driving..

Anyone know why this is happening and what do do to fix it..thanks:0

S500,

Sounds like it's not getting the enrichment it needs for cold running. This points to a temperature sensor (or the wiring to it) problem.

Is ti still under guarentee? If so make sure they honour it :)
