Snooping around the engine compartment of my
recently acquired 93, and I noticed something that
I have no idea what it is or why it's like this but I'm
sure there is a reason.

Mine is a manual trans, but up against the fire wall,
where if this car was an automatic and the tranny dip
stick would be, there is a hose with a bolt in it and a
hose clamp around it.

Does it have anything to do with the turbo simplification
by chance? It is right here.......

hey there. My car has one to a 1999, as far as i can gather its just a spare vacuume line, sometimes used to hook a temporary boosy gauge up onto, don think its anything to wory about

The arrow could be pointing to any one of many different hoses. A better picture would help a lot.

I'l take a guess and say that it is plugging the AWS (accelerated warmup system, to get the pre-cat hot quickly to combat cold start emissions). This would be a somewhat large hose (1/2" or 5/8" ID, IIRC).

could also be from eliminating the double throttle actuator without removin the solenoid and just pluggin up the hose...

I wasn't actually worried as it is obviously serving a purpose....just was curious so I can better understand what's
going on under the hood.

Sorry for the quality of the photos...best I can do for now.

Car lacks the aws...it just idles at normally rpms on startup....doesn't jump to 3k at all, atleast I am assuming it doesn't have it because of this.

I think its the coolant line that goes to the throttle body. Check the bottom, rear of the throttle body and see if there is a line connected.

Still kinda hard to tell from the pics, but I would guess that someone blocked off the coolant line that goes from the rear iron to the BAC.

Edit: Beat me to it

^ agreed. SOme remove that line from the TB. Check to see if you ahve a nipple on the bottom of your tb that is not being used.

goodluck,
