L337 Posted January 16, 2017 Share Posted January 16, 2017 So chasing a misfire I have developed over the weekend, I've been fiddling around the engine bay and I think I've knocked this vac hose off. Can anyone with a NA (or a very good knowledge of vac hoses) tell me where it supposed to go? As now I have a bad misfire AND a super lumpy idle [ANGRY][/ANGRY] Thanks!

ibby Posted January 16, 2017 Share Posted January 16, 2017 Look above the black bolt. Where the hose comes out from. It's the bolt above that, inlet plug on the right if you look carefully Quote Link to comment Share on other sites More sharing options...
Tyson Posted January 16, 2017 Share Posted January 16, 2017 As ibby says above where that vac hose comes out of you can see from the picture you took the bare metal stalk coming from the bolt where the vac hose attaches to directly below the other hose that's currently attached to the same bolt above the black bolt the problem hose is connected to.

L337 Posted January 16, 2017 Author Share Posted January 16, 2017 If I understood your description right, it's not a bare stalk, it goes into the inlet manifold :-( Thanks though! Quote Link to comment Share on other sites More sharing options...
Josh42 Posted January 16, 2017 Share Posted January 16, 2017 Does that one not go the MAP sensor? The black box with the blue label (far left of the picture)? Sure it goes on the bottom of there Quote Link to comment Share on other sites More sharing options...

Mike2JZ Posted January 16, 2017 Share Posted January 16, 2017 Connect it to the MAP sensor. Little black thing with the plug and multicolour wire in your first photo. On the bottom will be a vacuum port. Without it plugged in car will run like crap. Quote Link to comment Share on other sites More sharing options...
L337 Posted January 16, 2017 Author Share Posted January 16, 2017 I'll have to try tomorrow, out of curiosity - how crap would it run unplugged? Quote Link to comment Share on other sites More sharing options...
Mike2JZ Posted January 16, 2017 Share Posted January 16, 2017 I'll have to try tomorrow, out of curiosity - how crap would it run unplugged? Crap as in the ECU won't have a reference for the air coming into the engine so it will barely stay alive/low idle/misfire/stall etc. Quote Link to comment Share on other sites More sharing options...
