kinglarry001 fpr vaccume pipe, what does it do? esential part of the fuel rail-fpr? if you remove this while car is running, should there be a note change in the engine? acts differently? cause mine doesnt. unsure if this means my fpr is ****ed
kinglarry001 it runs the same if i take the pipe off the fpr end and cover the end of the pipe. but if i remove finger, then revs higher (cause obviously more air getting into engine. would of thought that by not having any vacume/suction on the fpr, then it wouldnt run as well.
