k so i got a 318i m10 that idle's at 1500 once warm and 1000 cold
and i cant figer it out, as its had air con disconnected
also i read that it can go 180km/h but down the motorway i can only get it to 170km/h
and once you get over 5k revs at high speed you can hear like almost sounds like bubbles of air in the fuel pump
i dunno im just guessing what the sound is and where maybe its just air get under a seal sum where
if anyone can help with the idle, it would be most appreciated
and if this is anything
only mods to engine are, K&N filter and new exhaust
oh and it had problems when trying to start on cold days , eg not wanting to idle and not wanting to rev past 3k
