Good evening all,

So I have noticed that my FD likes to idle hunt from 1000 to 1500 rpms. It would do this momentarily as the car was warming up. I recently just replaced the battery and noticed it wouldn't hunt anymore when the car was warming up. After thinking the problem was solved and taking her out for a joy ride, the idle hunting problem resurfaced. this time it happens when I shift to Neutral when coming to a stop. As soon as I stop the idle returns to normal and stays that way until I shift to neutral again when coming to another stop. My FD is running a Power FC, downpipe, M2 intake, Cat Back exhaust, and an upgraded SMIC. Is this a vacuum problem, tuning issue, TPS issue, something else? Thanks for the help,

- Luis

turn in the air bleed screw slightly until it goes away.

could be a misadjusted TPS/idle set screw though.

Check the thermo wax adjustment screw, if to tight it can also make it hunt.

Thanks for the tips! I plan to try and adjust everything this weekend.
