i cant seem to kick my cold idle surging, anyone have any ideas? i have a jspec swap with the acv blocked, but have retained the bac valve. i have checked all of the gaskets and such and it only surges during cold idle. after it warms up a bit it stops. any help is greatly appreciated, although this isnt a huge deal to me it is annoying. everyone thinks your car is all messed up when you start it up at first leaving anywhere.

 

get the manual.
go through idle set procedure.

 

Yeah^^^, jumper your initial set connector and see where she's at while she's warm. Although when that's off, you usually see it all the time...

You sure you don't have a vac leak that's sealing up when she warms up? I had something like that once, on a block-off plate...

 

i was kinda thinking that it could be a vac leak that is sealing up when warm, guess ill have to rip it all apart and find out! gee thats a first, lol! i have a batch of new gaskets and i am going to goop the throttle plate adapter section real good. ill let everyone know if that helps.
