Im so damn confuesed it shouldnt take this long to get the air out. im bout to jus take this p.o.s to the shop.....I cant deal with this shit any more
Check the seal around the brake booster...
My buddies CX that we swapped had a similiar idle surge problem...
The seal that goes around the brake booster (Circular thing in front of driver side firewall) was leaking...
Try running your finger around the seal, or spraying carb cleaner to see if the rpms change suddenly...
Good luck!
