Intoxalock

Starting shortly after my calibration of my device on 7/21, my engine started stalling and sputtering, and the check engine light came on. It was a code p0340 for the Camshaft Position Sensor. I checked the sensor and wiring all the way to the PCM and everything reads correctly using a voltmeter. I Disconnected my battery to reset the computer and the issues all went away for 2 days, and then the light came back and issues came back again. Getting in touch with a live person at intoxalock is near impossible as every option with their 800 number is automated and disconnects the call after making a selection. I reset my computer again today and the car is running fine again, hence it is not the camshaft sensor. I'm going to have to bring it to my service center on 7/27 to look at, and I'm really upset about it. My car was in perfect working condition until my device was calibrated on 7/21.
