I agree with raz but in addition check the ignition system.
Does it miss enough to set a check engine light?
I have found that the injectors have a small micro screen on the input side. I have seen them clogged if the residue gets past the filter.
The most common residue is sulpher that will by pass the filter. Change the filter and look for yellow residue. If so you have clogged injector screens.
If so let me know and I'll tell you how to fix it.
