I have a 1992 Nissan 300ZX it is not a TT or 2+2.if you are looking at the engine, on top are two adjustment cables. I know the far right is the accelerator cable but is the one on the left the idle adjustment cable? also is it best to have the accelerator cable as tight as it can go without have it pull on the switch or just a little loose?
On most cars, that 2nd cable is for the cruise control if it has a 2nd cable right next to the throttle cable. As for your other Q, most of the time the throttle cable has a tiny bit of slack in it (it's not loose by any means, but it's not normally as tight as a banjo-string unless the gas pedal is depressed from inside the car). There's probably no need to tighten it unless there's an abnormally large amount of slack (like if nothing happens when you initially press the gas pedal in the carotherwise it's probably just fine as it is.).
