Its going to be the one mounted to the bottom of your throttle body. It looks like a small black canister.

 

Thanks, but for the life of me I cannot find it. How big is it?

 

I will try to attach a diagram of where it is supposed to be. I simply cannot find it where it is supposed to be.

 

Well, apparently I am not allowed to post images until I have 5 posts. :/

 

Maybe this will count as number 5 so I can post a diagram.

 

I have looked under the plenum and I see nothing under there. Again, I truly appreciate anyone's help with this mystery location.

 

Look where it says TPS, it's right under there, it's a small black cylinder with a hose and electrical plug hooked up to it. It is mounted to the bottom of the throttle body.

 

Awesome! I was looking where the diagram was pointing to on the left of the plenum and it was right where you said on the right side of the plenum. My son has smaller hands and was able to get it out, although the rubber hose on one end was pretty much baked on and had to be cut. I'll just put a new piece of hose on. Thanks a million. I am trying to save this 2004 Tiburon GT Special Edition from the car crusher. It has 238,000 miles on it, but it's all long distance highway miles and the car is in awesome shape. The passenger side needs some minor body repair, but otherwise there is absolutely no rust. The interior still looks new. It does need new head gaskets though. I am losing antifreeze out the tailpipe, however, there is no oil in water or water in oil. I was about to buy the car from my friend, but because of the head gasket, he may scrap the car now. Is replacing head gaskets a DIY job. The shop wants $1400.00 to do it. The mechanic said something about magnafluxing (?) the heads for $400.00 and all including labor would be around $1400.00.

 

And by the way it could also be clogged charcoal box lines or the filter in with the charcoal box. See my diy for the filter here: http://www.newtiburon.com/forums/showthread.php?t=169076

 

Don't forget to think and check fuel pressure... sounds more like an overheating fuel pump... if it was charcoal or purge.. opening the gas cap would fix your problem

Since this thread is a decade old, I would guess it has been resolved in some way.
Next time, please look at post dates before your own post.
