I've just finished a JDM TII swap into my S5. S5 NA body and harness, S5 JDM motor. Everything is done and now it's having idling issues. I'm trying to figure it out but i just don't know what the deal is. TPS, BAC, fast idle, vacuum lines, etc... i just don't know. If anyone can come check it out, that would be awesome.

 

wrong section. mods please move to the west section

Dude, I'll try and get out there at some point in the near future if you haven't figured it out.

 

Why don't you explain how it idles and when (if not all the time) it idles, and maybe we can give you some ideas.

 

well it looks like it's not the ecu. swap for the NA one and still does it. The rpms goes up to ~5K and hangs there. i got it to drop down a couple of times to 2K but i would hit the gas and it would go up and hang. only for a little though then it would sputter and die.

P.S. MODS please move this to the regular west section

 

thread moved.

 

Sounds like a big *** vacuum leak. Check for cracks in your manifolds, or other places where the intake may not be sealed completely.

 

If this JC guy is right, grab a can of carb cleaner and spray, it's easier that way!

 

we'll see. i'll have to find some carb cleaner or wait til fri to buy some.

 

vacuum system has new lines. still having issues. boggs out trying to start but revs up to 3-5k after start. runs pretty good but hesitates/cuts out/bogs randomly. general 2nd gear 3-4K or off the line in 1st.
