Update!!

After the plugs and wires were replaced yesterday my car still wasn't running any different other than I was able to go over 20mph again. Today I had the wires tested and I was getting a weak spark on my number 2 cylinder. So a friend of the family that owns an autobody shop recommended replacing the coil. Had it tested and was running better but still jerking accellerating from a stop. Took the ignition coil modular to Auto Zone and had that tested and it failed miserably. So I bought a new ICM. It's running better, I don't have to step on the gas as hard to accellerate, HOWEVER on take off it's jerking before switching gears...and after having it tested again there is still problems with the number 2 cylinder. It's now been suggested that I have a clogged fuel injector. Anyone got any ideas. Does this sound right? My catalytic converter is fine that was tested and there are no problems. So I need to know if I'm on the right track.
I've so far replaced:
fuel filter
plugs
wires
#2/5 coil
iginition coil module
Thanks in advance for any information you can give.
