95gt misses throughout the rpm range
 

does anyone have any idea what it could be? i have a 95gt with the 5.0 and yesterday the car started to miss really bad, i changed the coil, spark plug wires, and checked each wire for good spark, replaced the cap and rotor, replaced the plugs, when i pulled the plug out of the #2 cylinder i came to the conclusion that it was not getting gas, so to be sure i started it up and did the good ol spit on the header test, and it was a dead cylinder, so i replaced the injector, but that still didnt fix the problem so i checked the timing, that was good too(13deg.) all the other cylinders are getting gas fine so im leaning toward a valve problem, there is no oil on the plug, so its not rings or the piston. if you have any suggestions of what this could be please reply, im starting to pull my hair out trying to figure this out thanks.
