KA Revs High when in neutral

[whippet]

Just swapped a 96 ka24de into my 95. Engine runs fine when in gear, but revs up to 3,000 rpm when in neutral.

From searching, I see people posting: sticking throttle plate, IACV, timing, MAF and such. But nothing definitive and nothing with my symptoms. Most complain of low or erratic rpm.

Any advice?

You could be idling high due to your MAF or any other air to fuel ratio based sensor, if one of your o2 sensors is unplugged, broken etc. Just trouble shoot her and check through process of elimination.
