    I have two codes on my 98 f355 f1 spyder, I had someone check out the codes but he couldn't tell me what they mean. I've done a bit of research on the P0410 and it sounds like the problem is from the air injection system but I'm not 100% sure. I couldn't find any information on the P0420 code. I also have the air suspension light on was wondering if it has anything to do with that? Anyone know what that means?

    How did you make out with your codes?

    The suspension light is unrelated to them. There is no air ride suspension in your car.

    P0410 is likely a blown fuse for your air injection pump. Do you hear a high pitched whine from the rear right during the first few minutes of start up? If not, check the fuse.

    P0420 is for bad catalytic converter. Are your cats original? Do you have high flow cats or test pipes installed? Either could cause this code. If you have original cats, one is likely bad. If you have high flow cats or test pipes, then you likely just need to install a rear O2 sensor spacer.

    Suspension Light could mean the following:
    -You started the car several times without driving it, it will clear itself when you drive
    -You have a bad suspension actuator
    -You have a bad speed sensor
    -You need to toggle the suspension switch to the other position
