yes i have k-pro and i srched for vacumm leaks i came up with nothing. take a look at the throttle body. there is this little hole(factory) when i plug this hole the idle drops to 800 and stops surging

Take the piece under the throttle body known as the IACV and clean it out,if that doesnt work go under Parameters in Kpro and go to Idle and adjust the slider bar towards the left and see if that works.

yea what he said... it might be rusted or clogged or something... also check to make sure that the wire is plugged into it. Then if all else fails u need to adjust it from kpro

in that case either the plug into the bottom of the TB is not plugged in poperly.. or u need to adjust it with the ecu... or there is a leak somewhere on the manifold

If i didnt change the coolant temp sensor from my d17 to my k20a2 could this also be part of the problem?
NO...

go buy a few cans of brake cleaner.. spray all around your mani where there could be possible leaks.... gaskets obetween the head and the TB. hoses attached to the mani and so forth.. if you spray and it stop surging then u found ur leak
