Okay, here's the deal. I bought my motor with this crazy 95mm nissan TB welded to my stock h22 manifold. I kept throwing a TPS code because it was a nissan TPS so I bought another stock h22 maifold and a skunk 2 68 mm TB. I finally swap over the upper plenum of the mani I bought along with the skunk 2 TB thinking this would solve my problems. Whn I did the upper plenum swap, I just made the gaskets for the TB and where the upper plenum attatches. Well, now my car idles at anywhere from 2500 to 3000rpms even after I adjust the idle. I'll adjust it and then after driving it a while it will jump back up like my throttle is sticking. I am also throwing an EGR code and sometimes a map sensor. I'm really confused at what I did wrong. Oh yeah, the stock mani that I bought was off of a 5th gen prelude. I didn't think this would make a difference because there were just a few vacuum nipples that were different. My friend said that the gaskets that I made might of blocked off something important since I just cut out the maid holes. Also, since putting on the smaller TB (which I thought would improve power), my car feels a lot slower all through the power band. VTEC used to engage at 5200 and now it's at 5400. I want to swap that stupid nissan TB back on and try to calibrate the TPS because of all these problems with the new settup. Let me know any imput on what you guys think. thanks

I had a skunk2 TB on my H22 when I first did my swap, the only problem I had with it was it smacking against my firewall, so I upgraded to a golden eagle TB. I don't think it's the TB, it sounds like one of the sensors or somthing that you swapped.

If you're planning on doing some serious tuning I would HIGHLY, HIGHLY suggest getting a Hondata S300. When I installed my S300 it felt like a dream driving my car in comparison to how I had it previously tuned, everything is on-the-fly and all those CELs you're getting it will display on-the-fly on a laptop.

edit: added hondata info.

 

you should definitly recut that gasket!!!!! also check to make sure that the TB and the mani are aligning right, the plate might not be closing all the way if there not. the vtech not engaging till 5400 sounds about right though. If you cant figure it out, by looking at it, I would just get the mani port matched to the TB and try it again. Make sure you have the vaccum lines hooked up right since you had to switch them around a bit too, that can cause funny ideling too.

 

Skunk2 TBs are very finnicky. I found that I had to adjust the plenum screw, the TPS, and find a couple vacuum leaks before my car ran decently. The odd time it'll go down too 500 RPM but it pops right back up to 800-1000RPM range.

 

I checked out the plenum gasket that I took off and it does look like I blocked off some holes when I made that gasket. One of them was to the IAC valve so I'm positive that's part of the problem. I also think I should lube up the throttle rotor because it feels like it's sticking a little. Any suggestions on what I should use and how to lube it up? Thanks for the replies!

Mine had the same problem. Just dump some lube on it and sit there working it in with the cable off of it. Eventually it loosens a bit, but your pedal will always be stiffer then stock.

 

can anyone verify that a 97+ intake mani will work on a 92-96 h22? If this is the problem, why waste my time trying to fix the wrong plenum?

 

Almost 100% you're good there. An H22 mani is n H22 mani.

 

it does have different nipple locations for vacuum but that's the only differences I see.

 

Okay, I made a new gasket with the IACV holes cut out. It still surges at idle (goes from 1000 to 1500 and then back down to 1000 repeatedly) and I'm still throwing a egr code. Are there any vacuum lines that hook up directly into the TB because I found a hole that is sucking in air. It's on the bottom but there is no nipple to hook a line up to it. When I put my finger over it to plug it up, it doesn't effect the idle at all. Any help from those who have the Skunk 2 mani would be great. Thanks for the replies ahead of time!

Okay...another update.

I jsut got my p06 back from j-k tuning and plugged it up. Now, it no longer surges but it's jsut lopey at idle. No CELs because the p06 is run for the egr. We'll see if the ecu fixes the problem....

If it's a JDM H22 with a JDM dizzy you shouldn't be getting a CEL for EGR.

My car was also doing the 1000-1500 routine at idle, when sittign at a light, etc. I double checked all my vacuum, and eventually it just went away. It'll do it once every once in a while but only once then goes right back to 800-900 RPM and stays there. Sometimes these things happen with swaps.
