Thread: Passing your smog test.

  1. #1

    Passing your smog test.

    Today I almost failed my smog test.

    It is common knowledge that the cats on the Z8 have to be hot to work properly, and get through the smog test, but today I thought that the four to five mile drive through traffic to my tire shop and back would be enough to bring everything up to temp, but it wasn't. The car failed it's first go around, and just squeaked through the second attempt, which is all you're allowed.

    When talking your car in for smog do a good 20-30 minute drive first, including a fast blast on the freeway, to really get everything cleaned out and up to temp.

    Great tip. I've always done the usual warm up, but I'll make sure to get a highway blast on the loop too.
