Knock sensor

322 knock sensor circuit abnormal voltage coming up on the diagnostic. How easy are they to change?. Also would it cause a kangaroo in 1st and 2nd gear. Does it when cold more so. 2nd gear foot to the floor it kangaroos
 
Have you found a decent place where to get the sensor from? I need to change mine as well, probably easiest to take the bumper off and go from the left side of the radiator, it's just under the lower intake manifold.
I guess it could cause your issues if it's gone faulty as it has to do with air/fuel ratio but better wait for someone who is clued up more than I am, usually kangarooing is attributed to the map sensor or aftermarket exhausts with unmapped ECU.

I've got a new map sensor miltek back pipes. All flashed ecu. I thought the knock sensor was above the oil filter on the back of the engine
 
Yes it is above the oil filter but at the front of the engine,I would replace the sensor and see how it goes.
Are you sure it is 322 for the fault code? Because to me that it's coming up as crankshaft position sensor circuit.
