Rough Idle in Neutral, But Not In First
So, I recently obtained an FD RX7, but I'm having a weird issue. When I got the car, it idled fine. On the drive home, the idle got a little rough. I'm not noticing any power loss or anything out of the ordinary. I'm concerned it's apex seals, I haven't been able to compression test it yet.
Here's what I've seen so far:
At idle, the car only pulls 10inHg.
When it's cold, the car idles at 500 really rough.
After it heats up, the car idles fine.
But as illustrated in the 2nd video, the car idles smooth with the clutch depressed in first, however if I move the shifter to neutral, the revs drop and it idles really rough.

I'm very new to rotaries myself and might not even offer any good help. But I'm assuming there are electronics, related to AWS, that can detect the gear select and changes the idle. Possibly something related to that system?
