Silicone Hosing = Poor/Lumpy Idle
sorry if mods think this is more of a techy topic, wasnt 100% sure which it should go in.
i tried fitting silicone hosing to my 156 2.0 today, between the MAF and throttle body, along with an external mini-k&n style oil breather.
im sure there are no air leaks, as everything is "on" properly, and all clips tightened right up, checked with "fairy liquid test" too, but it idles lumpy as hell, and goes to quite low RPM. drives alright though.
i tried an ECU/throttle rest, with no luck.
i put the old intake pipe back on between MAF and throttle body, and refitted the oil breather, and its 100% fine.
why might it misbehave like this?
does it "need" the oil breather, even though i read it should run cleaner without oily air going in?
