    If you’re in a jurisdiction where the law allows then I would suggest you remove the entire secondary air system and cap the tubes on the manifolds. You get a decent weight saving, eliminate a potential fire hazard and if you keep all the stuff you can always reinstall if you sell the car.

    And that means you get a permanent CEL on your car which fails your smog check and render your car un-registerable. Don't do it. Fix it.

    No CEL on a euro-spec 2.7 ;)

    as I say, depends on jurisdiction. Where I live my 25-year-old F355 is already classified as a car of historical significance and there is quite a lot of leeway. I recognise that in US the picture is different.

    Joe Cheung lives in Hongkong so no worries about CEL I would guess.

    It is strange that the glowing cat issue disappeared. I drove more than 10 times after that day and I didn’t see the cat overheat anymore.

    Hi Tom, I have a voltage meter to monitor the voltage. It always stay above 12 volts. In fact most of the time is over 13 volts. Alternator broke down last year and was replaced with a new original one.

    Hi Joe,

    Well, it was a thought. Still, you are somehow getting a lot of excess fuel in the exhaust on that right side. Have you gotten down on your hands and knees at the back of the car and sniffed each exhaust (not for very long, of course)? The right side would smell of a lot more unburned hydrocarbons. Not a solution, but would confirm that that side is passing a lot more fuel for some reason. Is your fuel economy suffering?

    Tom
