This two sensors provide signal to ICM at different RPM's. I think it is the 3x CKP that provides signal to ICM only up to 1200 RPM, and after that 24x takes over. Can someone else confirm this? The reason I need this info is because of the gas pedal vibration that I notice only up to 1200-1300 rpm here is why I think that I could have problem somewhere around this 3x sensor. We have all probably noticed by now that 3x sensor has twisted wires and that is to cancel out any interferences in the wires. (9 twists per foot is minimum) but I totally forgot about this rule and to protect 3x ckp wires from hot engine parts and exhaust I extended its wires so I can route them away from heat. So not only that my wires are 3 feet longer now but that 3 feet are not twisted. So I am wondering if there could be interference that is sending strange signals to icm only up to 1200 rpm. and that could create some ignition related issues (slight misfires). I am 100% positive that this is not vibration from engine transferring to gas pedal cable because I can feel that even if I use my hand to open throttle plate up to 1200 rpm. If someone knows more about this two sensors or this pedal vibration issue please help thx.

If I were you, I'd just twist the wires you added in. If it doesn't fix the problem, at least you can rule that out.
