Is there anyway to test if it's good or bad? And what would be a good brand to buy? Bosch?

There is a resistance test you can do jumping 2 of the wires with a meter and blip the throttle...can't access the online shop manual for some reason to know which 2 wires though
I replaced mine with a universal bosch from the auto parts which is the same sensor but you just splice it in and save $100
Maybe you can talk to him for me?
yeah me too. I spoke with a few guys including 505 about the casting mark issue and nobody has had issues with it with this batch. and so far, I am the only one having issues out of everyone who got a manifold from the 2nd group buy. Also looking at the flange, it doesn't appear to hit anything at all. So, Im ruling the manifold install out of my issue.
