    Not that hard to change one... knowing which one to change (and accurately determining the health of the other 11 injectors, as well as the fuel rails) is the hard part.

    Hello all. I spoke to Don about sending my injectors in for service and he referred me to this thread which is great. As I studied it in preparation to remove my injectors it seems that my 2008 3L is different (serial number 1B5449967). As I look at the motor and compare to the process above it may be a lot simpler with my motor?

    Just checking in for some feedback before I start. I will upload a couple of pics in a few min. Thanks.

    That's my write-up and engine in the FAQ topic and it was quite easy to do for the 2.5L. You might post in the 3L forum (what your engine is) for any 3L specific questions, lots of info there.
