I've had way more failures with carbs than efi.

I've had EFI run for 20 years with zero issues, on a single vehicle. Zero maintenance, not even sensor replacement.

One current vehicle is from 1985 and the EFI still works flawlessly... A 1985 EFI.

Once EFI transitioned from analog to digital, lots of little gremlins just went away. They became a lot more consistent and robust.

I've owned early analog EFI... Whew, talk about a persnickety system.

    I had an Isuzu Trooper with an early multiport EFI setup on a 2.6 4ZE1 engine. It basically ran on controlled vacuum leaks. The easiest way anyone ever found to fix it was to remove it and swap in a carb setup from a 2.3 4ZD1 engine. I decided that when coping with a 1980's Isuzu the most effective way to solve all your problems was the radiator cap solution: Remove the radiator cap and hold it up, then drive another vehicle under it. Put the cap back on and it will run better.
