Well i installed my aem CAI and now when the rpm drop below 1 the car idles a little rought, the steering wheel vibrates lol it didn't do that with a short ram ???? ANy ideas

also after installing the intake i hear this rubber rubing noise, i think the intake might be touching something because it's a 3' type r aem on a b18b motor so maby thats why, anybody had the same problem????
tahnx
