Yes you will need to replace 2 TB gaskets when you remove the throttle body. I would also replace the BISS screw O-ring as it can be difficult to remove with the throttle body installed (remember to adjust it when reinstalling). Now is also a good time to decide if you want to install a FIAV blockoff or bypass plate. You can also check your TPS sensor and adjust if needed.

EXTREME PSI : Your #1 Source for In Stock Performance Parts

Select Mitsubishi on the left, your car year (Eclipse 95-99), and then enter "throttle body" in the search box at the upper right of the page. That will bring up all the throttle body related parts on one page.

Enter "FIAV" in the search box to get the block-off plate and gasket.

I like extremepsi, but most vendors carry them

I forgot about the throttle body shaft seals. You can perform a boost leak test to see if you have any leaks in the TB. That way you will know what you need to replace, but I would replace them anyway since they're not expensive.

O-ring on page 1, TB gaskets and shaft seals on page 2
Search for FIAV for the blockoff plates

Refer to the manual under Fuel/MFI for TPS adjustment

Make 100% sure you count the turns it takes to bottom out the BISS, BEFORE removing it. That is assuming the ISC pathway was relativity clean.

This is all confusing me i need someone to actually show me how its done for me to learn anybody willing to teach me in person? i can pay cash if necessary.

I forgot all about this.... but you can buy a whole throttle body rebuild kit from snowborder714. Check out his page in the freelancer section.

Just to give you a heads up the 2 bolts that hold the throttle plate will be very tight and you will strip them if you don't have the correct size screwdriver. Well if you do strip them like I did you can get similar ones at home depot, remember to lock tight them in as you dont want them to fall out at WOT.

they have lock tight on the screws . if you get a mini torch from home depot and heat them up they will come out a lot easier .

Yea I figured that now because for the amount of torque it took to take them out would of stripped them going in. Now that I put lock tight on them I will be using heat to get them out. Sucky job.

It's almost easier to just drill the heads off the ones that are being a pain, pull it apart, take the stubs left out with vise grips, and replace with something nicer. Like an allen head bolt. You can put more torque on those later than the dumb phillips they put on there.
You may want to talk with snowboarder Blasted/Rebuilt Throttle Body Service - DSM Classifieds or extremepsi. Support the guys that keep this site going.

Actually it's much easier/quicker to use the correct tool (impact driver - hand tool) and a properly fitting phillips head bit.
