I got a 91 240sx and decided to clean the throttle body. I took it apart and one of the coolant lines that goes to the throttle body cracked. So i just decided to bypass the coolant from the throttle body. Then i found this other small hose. It has about a 5mm opening that goes to the throttle body. It is inbetween the coolant inlet and outlet on the throttlebody. Anyone know what that line goes to? It didn't have any clamps so i was thinking it is a vacuum line. I didn't connect it back and later I got a CEL. Don't know if it is related but it read EGR code 32. Also is there a throttle body gasket because i just used the liquid stuff.

exhaust gas recirculation, look around your exhaust manifold for where it goes

there IS a throttle body gasket. DO NOT use the liquid stuff. The other hose is vacuum. The coolant lines you don't need to worry about. I have mine bypassed too.

why bypass the coolant lines, whats the point of having them there in the first place then?

^^^ To keep the throttle from freezing and sticking open while driving in really cold climates...

Not and issue down here in FL, maybe it is where he's from in CA...?
