Help on fuel injector

Okay guys here is the problem. I just got the engine replaced under warranty but the car runs like crap. They now say it is a clogged fuel injector and injector seal and want $650 to do it. How hard are these to replace? I enjoy working on the car and if I can do this myself, I would prefer to. If it is a pita to pull everything I will just let them, but I hate to pay an bloated dealer cost if it is a simple job. Opinions.... thoughts?

I can practically guarantee that the injector is not clogged (unless the shop deliberately or knowingly clogged it).
That said, pulling the injectors is relatively easy. Just search.

I concur on the injector also....injectors don't plug easily...and don't fail very often

You have to pull the UIM and a few other parts..but not that difficult if you are a bit mechanically inclined....

Did they tell you which injector was plugged? And how did they figure that out

Not sure. It was running like crap after engine replacement and they spent 2 days (???) on the phone with mazda engineering trying to diagnosis the problem. I am not a fan of mazda techs but, unlike some of you, my knowledge only goes so far so I am forced to rely on others. This is not a feeling I like.
