I dont know... its essenitally the same thing as the KA one so if you can find that you should be set.Ryan

Your idle screw set properly? and also does it fluctuate up and down like it has a huge cam? Your TPS could be bad. How does it drive under load?

It's the unit held in by 4 bolts at the back of the intake plenum with a brown plug going to it.....take it off clean it with card cleaner,make a new gasket and snap her back on.,..if this doesn't help you no doubt have to set your idle switch.

i dont know about the idle set screw, how do i adjust that?

no it does not fluctuate much, when i let off the gas it will got down to 1000rpm, then go up to 1200-1800 and then stays there till i rev it up again.

it drives fine under load, has good power all around no sputting or hickups.

idle switch? is that the same as the idle screw?

The idle switch is built into the tps sensor,you have to check continuity while settig it...this is an issue with tons of rb swaps..thats more then likely it.

how do i check to see if this is my problem?

Make sure tps is set correctly. Pull the connector off, switch your tps to 20v scale, it should range from .4-4.0v Mine was at .45-4.03 for reference

Next, disconnect tps, start engine, turn iac valve clockwise until the rpm is at desired rpm. If that doesn't work, you can remove it and take some q-tips and clean it out or replace it.
