Hi all, First post to the forum. Guess that makes me the FNG ... Nice to be on board. I am the new (1 week) owner of an 86 GT, and am starting to do all the prep to drop the cradle. I'm pulling all the top side stuff first, and came across my first puzzler. On the front side of the air cleaner housing is a connection with about a 7/8" or so piece of tubing that runs to a black metal tube mounted via a bracket to the firewall right behind the drivers seat. the other end of the tube ends right below where the wiring harness goes through the firewall to plug into the ECM. The puzzler is there is nothing connected to that end. I've looked at some exploded diagrams, and it looks like this is called out as a PCV pipe. But I've got a different pipe that runs from the breather connection in the front valve cover and it went to a connection on the bottom of the tube between the air cleaner and the throttle body. Anyone have a quick and easy explaination ? Rember I'm new, so go easy on me.

That was replaced by one of the recalls.

You might want to disconnect that tube from the air cleaner housing and plug that hole. Wont draw air from the engine compartment , I used a wine cork, and then of course had to finish the bottle of wine.

I read what that was. I think one of the recalls, they were supposed to cap it at the air cleaner can (it is on my 88). Now if I could just remember what it was originally hooked up to......

Okay .... so these pieces are just ...abandoned in place ? I can handle that. And you're right I am a Fiero Newbie .... But not a car guy Newbie...... Been wrenching for 20+ years .... just most of my experience is on classic Mustangs.
Thanks for the info fella's And Like I said I am the FNG so feel free to slap me around ... Ya never know I may get to like it.

I'm new here myself. nice group of people here, helpful, and not condescending.
yeah, they leave that stupid tube on the firewall, I think cause there is a vacumm line also tagged to the same bracket....
now I'm gonna be up all nite tryin to remember where that line used to go....
but since I work nites, that isn;t a problme....

Yes you can get rid of it, the smaller line is the clean air for the EGR solenoid but all of the cars I have had didn’t have it hooked up.

The tube on the firewall was supposed to be disconnected from the air filter canister and the air filter canister was supposed to be capped. Most mechanics that did the swap were too lazy to do this. I removed the tube entirely from the firewall and took off the smaller tube from the EGR solenoid. You can add a filter like the cruise control servo uses to there if you want to.

Thanks ... now about this filter you speak of ... I just discovered my car has everything for Cruise except the proper T/S stalk (I think) ... So what does the filter for the servo look like?
