Wow I have had exactly the same problems ! I paid 1000$ usd they changed the oxygen sensors ! Then they found a lick on the vacuum sensor something ! The light still on with codes p0172 and p0175 and now is time for my inspection renew and I can't pass the inspection and I don't know what to do now! I have the computer so I deleted the codes but after 20 miles it comes on again ! I'm really tired of this car !! So much money ! Oh and to make it even worse I just got home from discount tire because my tire air was getting low every week I have to put air ! Well I guess the rim is crack so now I need a new rim also !!! I think just going to sell this car ! Any help anybody ? What could I do to pass the inspection ? Thank u
