There's a auto parts place called "Lordco", it's a chain similar to NAPA.
me : Do you have choke assembly for Q-jet carburetors?
guy : Those cars don't have carburetors, they are all FI.
me : What do you mean? A Q-jet is a carburetor.
guy : No, all the Infinity cars now are FI.
me : What Infinity car? A Q-jet is a carburetor, you know what a Q-jet is right?
(after about one minute of talking)
guy : Ohhhhhh....you said Q-something, I thought you meant Q45 Infinity.
me : .....
The guy did provide good help though, I ended up buying a bunch of K&N air filter stuff.
BTW, Lordco and NAPA are competitors here, which explains the similar amplitude of Dontknowwhattheyaretalkingaboutness.
