How to remove intake manifold Venturi tube 2003 Base
2003 Tiptronic Base
I am chasing an intermittent misfire on my 2003 base. I made a DIY smoke generator and did a smoke test on the intake system, and had smoke escaping in a couple of places. One was the connection of the intake manifold Venturi hose, to the intake hose that leads to the throttle body. I am trying to figure out how to remove this hose. Can anyone help me out, before I get frustrated and break something. Lol

Ok. Somehow I was able to get the file attached, without getting an error.

Hard to tell from pic, but usually vac lines like that require you to push the fitting together, pull a lip towards one end of the fitting, then pull the ends apart. Cant tell if this is the same type, but if so, it should come apart easily so dont go all he-man

you may want to try putting some silicon at the hose joint and that may solve the issue without removing anything..

Okay this is something I have not seen on Canadian/Euro cars. Can't tell you how that comes apart.
It must be a CA emissions or Tip thing.

Yeah. I have made tools to do that in a couple of fittings. I have some where you have to remove a clip, and hold a “lip” forward, as you pull.
This one has nothing like that. I have tried pulling pretty hard, pushing in hard, and forcing apart, by inserting something between the two shoulders. Nothing.

I agree. I have some flex seal. I was going to cut a strip, and wrap around the junction. Easy enough to remove, if I have to dig back into it.

That's a standard barbed fitting. Try hitting the hose with a heat gun to warm it up until it comes off easily.
