I bet one opens up when the engine rocks under load.
A vacuum leak would likely cause stalling though.Taking a throttle body apart isn't a good idea without an ODB2 reader and new gaskets. The gasket for mine looks like a keyhole and is $5 >
I suppose it could be cracked. Some cars don't like them cleaned (Nissan) or apart at all evidently. A lot of people on this one (reading) are just [censored] their money away trying to figure out what it is... while everyone typing online tries to guess what's going on (with even less information).

Yeah, I checked that.
