ok, i have a PO442 code, for an evap. emissions leak. it's going in the garage tomorrow to do a smoke tst to see where the leak is. does anyone know about how much this is going to cost to fix? or how much for the test? i'm dropping it off before they open in the morning, and i wrote on their early drop off form, a detailed discro\iption of the problem, as well as asking them to call my cell phone before doing any work. i want to make sure i can afford it now. there is no preformance problem, it just won't pass an inspection with the check engine light on. anyone have this done before?
