Unless something was replaced in the first 75k miles, my 23 year old Civic with 212k miles is on the original injectors, fuel pump, ECU and all sensors except the oxygen sensor. I replaced the fuel filter once, only because I thought it might be a good idea. And the tank rusted out, so that's been replaced. I like my complicated EFI.
I don't miss the 3000 RPM cold idle of my carbureted 1984 Civic!
