ka idles like ******
as an auto 240, idle was fine. didn't have any problems until we finished the 5speed swap.
it likes to idle a lot higher now. i've messed with the iacv, no luck.
tap the gas, maybe 200rpm and it will shoot up to 1500, sometimes 2k.
it decides on its own when to drop back down to normal idle, ie 750.
sometimes takes 15 seconds, sometimes 5minutes.
any ideas?
**** is really bugging me, especially in traffic, drive thru's. fawk

i just found out something neat. auto ecu's have a higher idle to spin the torque converter. if installed in a 5speed chassis they usually bump the idle up about 300- 500rpm depending on how your iacv is set.
usually takes a couple of minutes for the idle to drop back down. same problem that im having.
installing a 5speed ecu should do the trick.

the auto ecu will cause the idle speed to differ a bit but i don't think that's the problem. it sounds like the iacv is at fault. there is a plunger and spring hidden behind some sort of epoxy, next to the adjustment screw. i recommend you take the plunger out and clean it.

it's not that is goes out, what happens is that the plunger is more like a vacuum line. it tends to get plugged up with carbon. so the ecu ups the idle speed to insure enough air is coming in. it's probably the most common problem with all 240s that many don't find a fix for because the solution is hidden.
