high idle/rich mixture

[tramp_drift240]

ive got a 92 kade swapped into my pignose.

at idle, after warming up, the rpms sit at about 1k or so. it was idling at 1400 but i was able to use the idle adjustment screw to get it down to 1000. but theres no more room for adjustment, 1k seems to be as low as i can get it using the screw.

also, the a/f mixture is extremely rich. exhaust smells strongly of gas, and noticably spits out moisture which i assume to be unburnt gas or something of the sort.

anything i should adjust/check next? i just want a nice idle at 700rpms or so with an average a/f.

Did you start out with a 5 speed car or an auto? Just curious, since I just had this same problem swapping a 93 KA24DE into my '90 240, also doing a 5 speed swap at the same time. It was idling either way too high, or way too low, but I figured out a way to modify the wiring to fix it. I'm using an auto ECU with a manaul trans now as well, if that makes a difference.

originally had a five speed transmission, used the same transmission with the dual cam engine, using a 1992 manual ECU.

i wanna fix this.
