Hello, was wondering if anyone had any tips for idle surge issues. I had a code pop up for IACV which I fixed but still had the idle surge issue. I also have a crankshaft position sensor code if that matters to the problem. Some more info on the car is it’s a D16y7 with a manual swap done to it. It bounces at a decent pace around the 1500 rpms when I’m in neutral. Any help would be much appreciated.

 

You might need to adjust your FITV. Or eliminate it.
