Today I was driving around after school and I took off at an intersection normally, never drove WOT, and the car started to drive super rough. At every rpm the car sputters but still revs up smooth without hesitation, its hard to describe. The car shakes a shit ton too. Anyone know what could this be? New timing belt/waterpump ect overhaul was done within 500 miles. Fuel filter and spark plugs too. The car was running better than ever and right away started doing this. I tried a different/working afm from a friend and that hasn't done it. The rpms are also dropping after I rev it at idle, it will go down smooth to 750rpm then drop and rise again. This happened before and I fixed it and wasnt doing it today. Trying to undo this old o2 sensor which might be it, as I got an extra one from a friend too. Help!

Good job finding the problem.
Can you write up the diagnosis and solution ? Might come in useful for other members.
- really irks me when folks ask for help and then just vanish without reporting back when they find the problem. Doesn't help anyone else looking for solutions to similar problems ;DComment

We checked to confirm that the car was producing spark, and he changed the plugs, cap and rotor anyway to be safe. So that was that. Spark was present. Next things to check were fuel and air. Part of any fuel-to-cylinder check includes making sure the plugs in the injectors are tight.
He discovered that the #1 injector harness was missing its spring clip, and had slipped off the terminals.
*which, BTW, I have a good plug with plenty of wire for you*
