While every fuel injector had fired at once on the 4A-F, with two at a time on the 4A-FE (so one was firing against a closed valve), the 1ZZ-FE and newer engines fired each injector, only when the intake valve for that cylinder was open. Likewise, the electronic ignition of the 4A gave way to direct ignition on the ZZ and later engines.
