have an annoying problem with my s5 turbo 2, when the car is cold it revs/idles fine but after about 15mins of driving it starts missing and has bad hesitation through out the rev range sometimes at 2g then clears up and hesitate again further up in the revs and also starts idling bad jumps around and shakes the car. But only does this when the car gets hot and has been driven for a while.
anyone know what could cause this?

 

ahh mine had the same problem until i adjusted tps. maybe yours is bad or out of adjustement? what mods have you done to your car? if you did the throttlebody mod your tps will be off most likely
