    Emissions fail - PULSE AIR SYSTEM for G54B - Colorado

    Hello All,
    New to this forum - thanks for letting me join!

    Here in Colorado, I took my newly acquired 1980 Plymouth Arrow (thanks Scott) to the emissions station and was failed as I need a Pulse Air System.

    Can any of you fine folks educate me on this and perhaps have one laying around for sale? Mr. Google was full of hits but not much I understood specific to vehicles. Thank you all! - Dana

    That is also known as a reed valve - it draws air into the exhaust manifold to help the cat burn off any unburnt gas. They are really hard to find, and even harder to find good. I have an 86 2.6 that may have a good one - I will check and see tomorrow.
