so i finally have my swap done, from ka24e, to ka24de, but the car won't idle right, i think i have managed to connect all the wires right, but it's still idles high. When the car has been running for a bit, it start to idle up then down, i have changed over the e.c.u, so i have no other ideas, if anyone can help it would be appreciated

 

tried adjsuting the idle screw ir cleaning the air valve for it?

 

Ya i did, but something else came about, when i unhook the vacuum line from the idle air control to the intake tube, it runs fine, but when i hook it up, the car stalls, any ideas?

 

I've seen IACV problems on many different nissans. Trying holding the throttle open just enough to keep the car from staling and run some seafoam through the iacv. If cleaning it doesn't work then try taking it apart and see if the membrane inside is broken. If it is, get a new IACV.

 

thanks i'll try that, and let you know

 

so i switched the IACV, and still the same problem, i did clean it out too. I pretty much lost for what else to do, so if you have any ideas that would be appreciated

 

try some carb cleaner on the maf

 

See i think the probelm is not in cleaning, i think that it not hooked up right, see when i hook up the big vaccum line for the idle air control, it stalls, but i don't know where the other line feeds too, beside the big vaccum inlet on the airt intake tube, so if you know where it go that would be a help
