I'm trying to figure out if it's safe to use a good fuel injector cleaner like Lucas or Redline, but it seems to depend largely on whether I have pintle or pintle-less injectors.

They changed somewhere in the 93-94 time frame, and my car was built 01/93. Any way of telling what type of injectors I have?

Very simple look at your injector connectors

If they look something like this they are the old style.
Pintle or pintle-less Injector_Connector_Square

If they look more like this then they are the new ones.
Pintle or pintle-less Injector_Connector_Oval

Also I don’t think a little bit of Lucas will hurt either one just don’t over do it.

Thanks, Tony, good pics! Looks like I've got the newer pintle-less injectors, yay!

Also found this thread on plenum/injector replacement with pointers to Courtesy Nissan parts pages which splits 90-93 for old and 94-96 for new, hence my confusion:
