i did the S13 black top swap in my 240sx. my car starts and everthing revs through all rpm freely but wont idle, once i let the rpm drop below 1,000 it dies out. my shop told me it maybe the AAC VALVE (idle air control valve) i wanted to know if it is the same part from my old motor the KA24 DOHC

PLEASE HELP !!

it could be that or it could also be your throttle plate closes ooo much at idle, there is a lithe screw and nut thing on the bottom of the throttle body adjust that so you plate stays a lil more open

hmm okay i guess i can try that but would you happen to know if the SR AAC is the same as the KA AAC VALVE

Thank you

Throttle position sensor?

KA AAC and SR AAC are not the same.
The TPS is from a 91 (or similar) SE-R Sentra, incase you decide to try that.
