I need to give my 03 a tune up. How do you get to the rear 3 cylinders? I was told something about having to take the intake off.
Is that correct?

 

You have to remove the cover, but not the intake manifold.

 

Does anything else need to come out to get to the spark plugs?

 

Actually for the plugs, I don't think you even have to remove the cover. But I did it anyway so I didn't break it by leaning on it. Other than that, nothing has to come off.

 

So I just move the ignition modules and that's it? Really have not had much time to look at his so far, so any heads up ahead of time are greatly appreciated.

 

I'm assuming you are talking about the 3.4L. I was talking about on my 3.8L, but you still shouldn't have to remove the intake manifold for the plugs on the 3.4L. I never did them on a 3.4L, but I can't imagine it being too much different. I know the coils are mounted back there so yeah, you might have to move them.
