2G Rebuilding throttle body

[Sjd6795]

So I just removed my throttle body and I noticed this tan sensor was plugged in and I assume it's the FIAV? I also noticed the two coolant hoses are not connected and I assume it has been bypassed?

Look at Jafro videos on youtube. He cover the rebuild of the throttle body. I did mine last year with help of is video.
Also, the tan connector is the ISC (idle speed control)

The tan part is your idle speed control, and to the right is the fast idle air valve. If there's no lines running to the FIAV, they've bypassed it.

should the seals be hard to press back in?

For me, the throttle body shaft seals took some time. Hard to remember since it was a while back. Make sure they’re lubed up.

 

[Sjd6795]

I don't have any lube unless regular oil would work to help slide them in.. But these things just won't go.

If that’s all you have, I guess. Just use a light layer. Yeah they were a pain. Maybe try a small socket and GENTLY tap it in

These are the ones that I got https://www.extremepsi.com/store/Th...tsubishi-EVOLUTION-VIII-and-IX-2003-2006.html
they recommend installing upside down then flipping over and doing the correct way . They sent me 4 seals total because they probably knew my Dum**** would mess some up.

Anyone have a guide for a throttle body delete?

 

[AWD-Tony]

Yes. You can remove the entire motor

I got my shaft seals inserted and everything put back together exactly how it came off INCLUDING the TPS. But I can hear an even larger leak now and the idle sounds like sh**. Almost like it's cammed.

Find the leak

 

[Sjd6795]

Hopefully the car will run well enough to get it to my dads house. He has more tools and a garage and I need that for sure.

if i remember correctly when i did mine, i used a tiny bit of grease and a 10mm deep 1/4 socket and lights taps from a hammer

Crazy idea here... But @snowborder714 makes this tool specifically for replacing throttle body shaft seals. I bought the tool when I replaced my seals, WORTH EVERY PENNY.

A few comments:

• Just because there were no hoses running to the FIAV nipples does not mean the previous owner properly blocked off the FIAV. You need to check and see if there's a plate between the throttle body and the FIAV and ideally what type of plate (bypass or blockoff). You'll be able to tell if this thin plate is installed just by looking at the throttle body (no need to disassemble). From what I can see, there is no plate installed, which could be the cause of your massive air leaks, which would be out of the two nipples. I'd expect to see a bit of the plate here where the two pieces come together.

  This will determine if your ISC is even able to function or not. The bypass plate has holes in it that let air from the throttle body down into the FIAV so the ISC can do its job, whereas the blockoff plate is meant to be installed by itself and just remove the FIAV (with the ISC) entirely.
  
  
  
  
  
  
• If the shaft seals are metal cased, you'll want to use something to install them and not bend up the case. The tool I sell is the best method, but I've used a screwdriver and a properly sized socket before with some success. The real issue is some of the shaft seals do not have a chamfer on the edge that goes in first which means it will not help center itself so you need to install it as straight as possible. If the shaft seals are not metal cased, you can press them in with your fingers. Always use some dielectric grease when installing any shaft seal.
• To find the leak, use soapy water. Spray it all over the area and watch for bubbles.
