air leak how do I fix it
First thing to do is run a refrigerant with a sealant through your system the next time that it blows hot, it that doesn't help you will need to have a tech look to see what parts need to be replaced.
Greasy, he might be talking about a vaccum leak. Check all your hoses and gaskets. I usually have the engine running in park, pop the hood. Move some hoses around and see if you can hear some hissing. Spray some carb cleaner around suspected area's and see if the idle increases.....http://www.aa1car.com/library/vacleak.htm
Air leak form where, tire, vacum hose, air condition or EVAP ?
