KA24DET Idle Problems

[s14inwashington]

I have a 96 240 SX SE with custom turbo kit. no vacuum leaks, tried MAF in charge piping and MAF before turbo inlet. right now it is before the turbo inlet. Idles like **** when cold, fine when warm. Why does it want to hesistate and die? my BOV is open atmosphere. and i would like to keep it that way, and im running 5 lb so id like to use the KA MAF also. I searched the forum but couldnt find a straight answer. ALso, where should the 2 hoses that normally go to the OEM plastic intake pipe go? one is for EGR and the other is the valve cover breather. If it means re routing my BOV to the intake after my MAF but before the turbo, then so be it. but until then, i want to know if anyone else has a solution to my problem thanks!

ummm, I think youd get a much better response, in the ka-t section. Repost there. as far as the questions go, heres what I've come up with;

Where did you put the MAF exactly? I know you said it's before the turbo inlet, how far before? You want it atleast 6" away from the turbo for accuracy purposes, if it's closer, it will cause idle and hesitation problems because of misreading.

The hose that runs from the intake to the valve cover isn't needed. Pop it off and put a filter over top of the valve cover nipple and cover the nipple on the intake pipe. I'm not sure I follow you on the EGR inlet, usually that's on the intake manifold somewhere. I could run out to my car (its 6am right now, not happening at the current moment, lol) and see what your talking about though.

Hope I've helped a little.
