Hi I have an audi a4 -02 vith a issue, it goes well in lower rpm and easy throttling but when I put my foot down and reach about 1700rpm it jerk hard almost as if it's misfiring , been to the garage and they are guessing on the pump or injection, they have found that one of the motorpads(?) is defective giving a faultcode on that sensor, what does that sensor do/control??

apprichiate some help

with regards Pata
