Whats the lifetime on coils, injectors?
Just wondering if anyone has had these fail, and at what mileage. And if so, does the car give any malfunction messages in the speedo display?

injectors hardly ever fail. they may leak or be dirty, but that shouldn't happen until well after 100k miles.
As for the coils, they should also last a good long time. There will always be freak occurrences of early failure, but on average, these parts should easily make it to 100k.

Thanks, i suspected something like 80 to 100k based on experience with other cars.
Im at 120k, and have an occasional misfire to track down. When I replaced valve cover gaskets earlier this year, I cleaned all coils and inspected them for cracks. Also changed the spark plugs recently.
