Might need to turn the idle speed down, Theres like a screw somewhere around the throttle body i think.

no dont touch the idle speed.

DID you "trick" your ecu with the resistors to make the car think its in neutral?
if it thinks its in drive the idle will be a bit high.
also the ecu needs to know or be "tricked" into thinking the transmission is at normal operating temperature - another resistor..
but it wont work 100% as it would with a manual ecu, but trying to find one is like finding hens teeth OR a virgin kiwi chick LOL..

The manual ECU's pop up on ebay fairly often... I know when i was looking for mine there was about one a week. Ended up getting mine for $70 Delivered Which was bargain of the century

Lucky bugger, i paid $170 for mine and i thought i was lucky!!

The resistor trick should bring the idle down, just have a look at the tech doc. Be aware that a couple wires might be different colour to the document, and thats where a workshop manual comes in and a bit of thinking so that your not using a solenoid wire like orginally did.

also
you need to add resistors to trick the ecu so it thinks the car is in neutral.
this should bring your idle down.

also you need to add a resistor for the trans temp . otherwise the ecu will think the trans is overheating (no signal from sensor)and your thermo fans may run constantly.

I did it too, but it would idle a bit strange every now and then. They dont make for nice driving when the power steering pressure switch dies, the rev's were going spastic hehe
115 bux for the ecu
