Lol the same way as they check with flat tires. Take a empty windex bottle fill it with water and alittle dishwashing soap shake up the bottle and close it. Start with each wheel well and spray with the bottle all over the top part of the airmatic shock. Usse a flashlight to see if there are any big bubbles forming and if there are that means its leaking

OK cool...I figured it was just that....but you never know....

Do I need to raise the car by pressing the airmatic rise button in the car?

I also looked at the car and it seems that the front is sitting higher than normal. when I press the airmatic up button, the car rises as I notice the back go up, but then when I take the airmatic off, the front doesnt come down....

any ideas as to what that can be? If was a leak, I would think that the front of the car would be sitting lower...

its nothing the car does that to me sometimes too. All that you have to do is press the airmatic button one more time and itll go back to normal. Or you can try the 80mph trick. If you go anothing over 80mph in these car they automatically lower themselves for safety to be more stable but id try the first way lol.
