    Hello. Has anyone had to replace a fuel injector on this engine? If so, how? is there a more efficient way then taking engine and transmission out?

    I read somewhere where a person attempted doing it with the engine in the car, and he unknowingly ruined a seal which dumped fluids on start up.

    Awesome, thanks. I subscribed to that for future reference now.
    He was quite a competent mechanic so I feel like if he had such an issue, this isn't really a DIY project for the 'shade tree mechanic' like most of us. lol

    The only right way to do this is pull the engine. It was quite a task trying to do it with the engine in the car.
