ricewjx,
I live in PA. Each year for the past 3 years I've taken my car in for inspection with the check engine light on ...... they fail it and charge me an extra $ 50-$100 to full around with the emmissions and turn off (reset) the check engine light. The light comes back on within a couple days because of the P171 & P174 problem(s). But I'm happy to say .... not this year. I did the fix and the light has stayed off. It goes in on Monday to be inspected.
