I fixed the issue, the one-way check valve hosing that goes into the vac chambers under the intake manifold was broken and also one of the vac chambers plastic pieces broke. Pulled two vac chambers and a one way check valve off a Probe and now my MX-3 is in working condition.

http://img40.imageshack.us/img40/5401/coldair.jpg :D I put that vac hose on the second connector right below the TB since it fit almost perfectly for now. (gonna change it a bit down the road though). Thanks for all the tips! BTW I know the setup may look funky but it worked out quite well and rest...

What would I do about the vac hose that goes to the FPR?

Ok, I've been breezing through the FAQ and looking at custom Cold air intakes and what not, can someone give me the dimensions of the Throttle body on a 92 MX-3 GS (V6 K8)? Is it 2.5"? Also, can I fit the VAF into the bottom of an K&N air filter without using a coupler? I'm trying to compil...

Ok scratch everything I just said haha, I went to the auto store and it looks like they sells chrome (i think its chrome...) piping and attachment stuff for intake systems and I'm just gonna buy a few of those and maybe a K&N filter and call it good lol.

Lol, yeah I'm debating on doing it myself. I just sorta want it to look really nice instead of like I just slapped some crappy looking PVC stuff together or something though lol.

Does anyone have any suggestions on which setup/brand to buy in regards to a cold air intake? My entire accordion tube on the air intake is pretty messed up and patched. If I put the cold air intake in will I see any noticeable differences?

Also, I checked the ohm reading on my IAC valve and got only 2-3 ohms, and the book stats it needs to be like 10.7-12.3 (when car is at 68F) but my car wasn't fully cooled down, does that matter? Aaaaaaannnnnddd (lol) would the IAC valve from a probe's V6 engine fit the exact some on my throttle bod...

:evil: :evil: :evil: :evil: :evil: I found a bad vac leak in the vac chambers and one-way check valve and have replaced all the parts and the freaking car still SURGES. I can't freaking believe this crap, I'm so close to just selling this car though. It definitely CAN'T be a vac leak i dont think. C...

Ok. Looks like I'm gonna take off the intake manifold tomorrow and try to just jb weld that part together to the best of my ability (it broke the plastic spout that comes out of what im guessing is the vac chamber in the intake?)

Sounds like I for sure found the idling problem on my car then :) which is definitely good news. Do you think this will work the same though? (if i can't find one anywhere at the wreckers) http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Vacuum-Check-Valve-Universal-Dorman---Help_5...

It still affects the VRIS? It doesn't go to the VRIS at all, it drops off that spout and goes below the intake mani (on the outside) and over to where the cyl 3 is into something else. Would the link I put up be a good replacement? I'm outta options =/

With a bit of research, it looks like it's a one-way check valve?

can i use this as a replacement?

Omg...I for sure found my vac leak problem.. but have NO IDEA how to fix this and what it is even called/does? Please someone see if they know anything about it and if they know a place I can buy one. It has a hose that attachs to a metal spout on the intake mani right next to cyl 1 that is this thi...

Yeah I'm hoping it is causing the rolling idle but idk. I JB welded the piece back on as a temp fix and will throw it on later today.
