We did our injectors this spring. My boyfriend (Brodie) is a mechanic
, and we are very DIY. However, the injectors are the only thing we've taken in to be done professionally as Brodie's opinion was that it's too specialized to do ourselves. We have a three cylinder Isuzu from the 70s that we'll do a rebuild
on next year. Doing the injectors made a big difference in the vibration issue we were experiencing. Having all three serviced by Fred Holmes Fuel
Injectors here in Vancouver (they have another location in Prince George, though I'm sure there's someone locally who can handle them) cost under $300. It was a two day turnaround from drop off to pickup. I talked to their service
tech afterwards and he suggested having them done every 1500 hours.
