    I finally got my scanner in, and scanned the ODBII to get the following:
    P1445, P1448 and P1449.

    Ive read some of the threads on possible reasons, and think I will start with first getting the SRI kit installed to see if it makes a difference. I have cleared codes for now and will let you guys know if it comes back immediately or after XX miles.

    Also, the car is VERY loud. It has stock headers, cats and a tubi exhaust (which was installed AFTER the PPI, CEL came on about 10 miles after this). It seems louder than it should be. Also, at initial start up, there is a high pitched buzz (nonstop sound) that disappears after about 5 minutes of running the engine.

    Anything I need to concern about now until the light returns? Or wait and watch?

    Also, my shock absorber light came on today when checking the OBDII - Ive driven it 150 miles without any issues, and it came on today when the car was standing still. What I should be looking at.

    Thanks everyone!

    Those are codes for bad cat ECUs. All 3 of them. Does your slow down light come on?

    Also, the high pitched noise at start up is normal. That is just the secondary air injection running for emissions purposes.

    Nope, I do not have the slow down light so far. Where would I look for the ECUs ( and what would I look for in a visual approach?)

    Thanks

    My suspension light comes on if I start the car and let it idle. I believe it is because the ecu is looking for a speed input and does not see one. As soon as I drive the car the light goes out. This seems to be a normal operation. Does the slow down light come on when you turn the key to the on position? When I got my car the PO had removed the bulb for the slow down light. From the codes you got I think someone has unplugged the CAT ecus.

    1448 bypass thermocouple, 1445 right CAT thermocouple, 1449 left CAT thermocouple, make sure they are not loose at the thread.

    The slow down light works, as it came on briefly during a drive (for about a minute) and never came back on except during the startup check. I looked in the engine area and saw the following 3 unplugged wires - all on the right side below the right rear bulb housing. Are these the ecu wires? Or something else?

    Yep it looks like your ECUs are unplugged. You should also have one loose wire on the left side too.

    I'm getting these codes also but my connectors are plugged in and I'm still trying to figure out if it's the ECUs or the thermocouples.

    Your CAT ECU connectors should lead to little green or black boxes that sit to the side on the driver side and behind the wheel on the pass side (item 69 in pic)

    The cat ECUs already have plugs in them - I found them behind the rear pax wheel, and all the ports are already plugged with wires. The 3 hanging are still without a 'home'.. any ideas???

    I don't think it will. It's a link to the same 7 year old message thread ;)
