Why will this help the idle and ecconomy? Is the stocker split?

I believe my stock one is split, as when i push down on the intake pipe the car stalls. have tried new afm (twice) and o2 sensor. Hope this is the problem. car idles like shit and blows smoke.

on a gc8 you will have to remove your maifold to install one properly. keep that in mind and get a set of gaskets.

just replaced inlet in my99. get a mate to help lift manifold out, definitely when installing manifold. bit of a pain bye yourself.

got the hose under the manifold with some good lube action. But the BOV return outlet fouls against a fuel rail bracket. Geez i love aftermarket parts! Also when i removed my cooler i found a sensor unplugged. May have changed the hose for no reason.....Yay

there is two fuel line brackets. i took fuel lines out to install pipe when manifold was off.
if a sensor was unplugged the engine check light should come on?

it was a blue plug going on to a sensor with a vac line running to throt body. No check light tho. Even if i remove the fuel lines to fit hose, the lines will foul when reinstalled. I am going to have to either bend the bracket or shorten the outlet on new hose, as i am not running bov return anyway

my was slightly in way. i also cut 20mm off end because it was to long. most likely you will need to shorten some of the other pipes as well.\
dam aftermarket parts.

Same here, i am using a factory bov, and had to make some new brackets for the fuel lines and the bov line. i also had to shorten it by about 30mm.
