I had a smog test in NV last year while visiting. It flunked. I soon to move.

What is your question?

To NV and want to repair it before I do. The NV repair shops are very expensive as to AZ. I'm told its not that difficult of a fix that is under or around the distributor. The report said: "High Speed CO 3.03% Greater than 1.20% and High Speed HG 227 Greater than 220 parts per million." Can anyone give me advice on this and how to fix it. At that same time of the test I had a few small holes in the muffler. I replaced it. Do you think that had anything to do with my van flunking?
