Found a small breather hose that goes from the pollen filler housing to the inlet manifold with a rivet stuck in the end, so i unplugged the rivet and refitted the hose to its hole, anyway, driving around with it attached whenever i put my foot down on the accelerator something would suck air from the cabin.
it got quite annoying so tonight i refited the rivet and the 'sucking' has gone away. performance has also increased.
also, removing the rivet i used my finger to plug the hole and then unplug it, the engine would idle better and the exhaust would not blow asmuch when it was plugged, where as with the hole connected the exhaust would blow and the engine would idle with noise.
confused as what the hose is, can anyone tell me what it is
