A development of the computer controlled sequential port fuel injected, electronic ignition engine is the most significant feat in automotive history. According to my late grandfather, up until that, the most significant feat was tires that actually held air reliably.
The rub for me has been that most drivability issues which I have encountered with the computer engines has been due to non-functioning sensors and not engine components. Trouble shooting can be a nightmare, and god save you if the problem is in the spaghetti-like wiring harnesses.
