You shouldn't be getting fumes in the rig just driving around unless you're also doing a lot of just sitting around.

If you are driving and getting fumes in the rig, you likely have an exhaust leak or the tail pipe's been cut too short or you have a hole somewhere in your floor.

As for the high idle, I'm sure someone else might have insight on that.
