Yep has aircon and is very clean! Just have to fix this magical idle issue. OH i forgot to add (don't know if it's important), but the car doesn't have an o2 sensor yet. There's wiring and a plug for it, but the previous owner just had a 1-wire sensor dangling around in the air. I have ordered a new 4-wire sensor and it will be here in a day or two.

I tried pushing down the dashpot rod by hand, to simulate the vacuum, and no such luck it didn't have any effect
