Brother, I'm facing the same little-vibration-on-idle-when-AC-is-switched-on-issue, what seems to be the culprit? The car has a manual tranny.
Also, will you be kind enough to enlighten me how much a "tuning" should set me back? I was also told to replace the Power Steering fluid the last time I got my car checked (there were no leaks), how much does that cost from Honda 3S?
I bought the car used like 8 months back but it has only been driven 3k since then (it had around 60k on the odo then). I'm not sure what kind of a maintenance-schedule this car was on under the previous owner, so what should I be getting checked? I was told of a "general check up" the last time around, any idea of what that includes?
