So I've been working on my car at school for the past few days and figured to check my engine over with a smoke tester to look for any possible vacuum leaks.

Now for the part that I find strange, there appears to be some leaks around all of the places where the throttle controls go through the throttle body. Like where the TPS is located and even on the firewall side. Now they aren't huge leaks or anything but leaks non the less. Are these normal leaks or do I just have a weird throttle body.
