Gotcha, I think the valve and solenoid you are referring to is the check valve. Part number: 12619125. There's a good pic on Ebay (*Note, I know nothing about the seller, just linking for the pictures sake) BRAND NEW OEM SECONDARY AIR INJECTOR CHECK VALVE 12619125 FOR BUICK AND PONTIAC | eBay
On mine at least the bracket wraps over the bolts and the only way I can see to get to the bolt heads is to cut the bracket. I do have all the tools and such as I have my own shop and have been busting my knuckles for years.... just have never run into something installed in such an obnoxious way. It's odd, I have done plenty of emissions valves on other vehicles and some could be tricky to get into but were always doable - this one it is like someone bolted the bottom down, bent the bracket backwards over it and bolted it again. I would just remove the top bolts and bend the bracket back but there is no room behind it.
I would love to just delete this but when I tested by just unplugging everything I got even more error codes and unfortunately, while I am a programmer and even do assembly, I have never played around with ecus/ecms. Anyone know if I could just unplug it all then swap the ecu for a non cali-code one?
