I have come to that conclusion as well I have two bosch sensors coming next tuesday thru amazon,I put the stock bad sensor back in,wot no throttle cuts or nothing drive back home reinstall the the oreilly sensors,misfires throttle cuts so yes its got to be the sensor,odd thing is the stock factory sensor is great until it get hot and you cut the car off better wait at least 20 mins to restart ,anyway thanks for the info small things just work my nerves.
