    Yeah after I changed them. I don't see how those two sensors would cause a jerking problem though...

    Cam sensor helps time the injectors with the spark event. Plays a major role if the jerking is misfire related.
    Describe what you feel a little better.

    Let's say I'm going maybe like 20, 25 in 2nd gear. It will jerk maybe 2 or 3 times. It feels like I let go of the throttle and step on it real fast again. And it will do that once I shift into 3rd, 4th, and 5th as well. Sometimes even when I'm starting off it jerks even before I let the clutch go all the way. Maybe I should take off the cam sensor and put it back on again? Just in case I put it in wrong (which I HIGHLY doubt) lol.

    Its possible. I know that some have an alignment pin/notch. You have to slightly open the throttle b4 you put the sensor on. If not the voltage will be way off for the ECU to read.

    I'll definitely do that man, I'll change the fuel filter just in case as well, it's only 10 bucks anyway.

    it has nothing to do with what you stated... but a bad engine mount can cause jerking also

    Not really. All the motor mounts were out in my DA, it just shook bad.

    Only said this, cuz he said that it started AFTER he changed those sensors.

And I cleaned the mass air flow sensor, changed spark plugs and spark plug wires because I thought those were causing the problem but I guess not. Anyone know what's wrong with it?
