I have checked the spark plugs, wires, cap, rotor, replaced the injectors, and have checked the hoses. The car shakes when running and has very little power through out the rpm range.

Ok. I ordered a compression gauge and will check them when it gets to me. I think I have a stuck valve from carbon buildup, as I also failed smog due to high nox.
