Default Low/Rough Idle

So my 82 924 N/A has been running great for the past week and a half, until it just recently rained. I'm suspecting an ignition component got wet and is causing my car to idle very low, about 500-600 rpms. It idles there very steadily, it isn't fluctuating or popping at all and the throttle response is fairly decent. Where should I look first?

Vacuum leaks...you should check for split hooses, cracked hooses..stuff like that.
Also, get a new cap and rotor...always nice to have those fresh.

Will do, I've checked the entire ignition system and still no dice. That's definitely my next move. The cap and rotor are still good, less than a year old. Let te vacuum leak hunting begin

Hi,
I used to have 1978 924 - back in High school in the late 80s- please make sure the hood is not shorting the distributor on the top - My front hood was misaligned when I ran into a table - I forgot my foot was on the clutch and first gear and it lunged when I lifted my foot off the clutch... not happy...
