the sensor is ecu grounded and shielded. however i have spark plug wires in the general area but a solid 10+ inches away. ive got some plug wire shielding in my tool box. im gonna install after painting its bright *** yellow black with rubber coating. i pulled them further away and it runs smoother. so i know its at least an issues. however the power wires to the coils run parallel to the crank down the back of the block for about 2 feet. gonna try and sepwrate those as well. see if i get somewhere with that. i wonder as well id coil drivers can cause this as well. as they are at the hub of the ecu harness.
