when i connect the afr gauge (sunpro with all them LED bars) my car starts to stumble and shuts off. i connected the the o2 signal from the afr gauge to the primary o2 wire that leads to the sensor( so its before the sensor plug). any ideas of why it does that. its a single wire o2 sensor too. not running a 4 wire sensor because i used my single one from the 5s when i was doing the swap incase it sounds weird.
