i dont think that there is any fuel injected 260, i think someone stuffed up by putting the e there.

In australia we didnt get the 280Z, we only got the 240Z, 260Z, then went straight to the S130s. So our 260Z ran from when the 240Z stopped up until '80.

See, I thought this would be like a blogronym thread. That's what I need, I've figured out so far

FWIW = for what it's worth

What the crap does IMO stand for? LOL

Oh, P.S. LOL = Laugh out loud

lqtm = laugh quietly to myself (more truthful version of lol)

Okay sorry to hijack, please continue... :D

Did you get AAC? I can't remember what it actually stands for, when the engine manual refers to it using a full name, it usually says idle air control or something, odd.
