bosch vs ngk/ntk o2 sensor
Hi, my 90 si has hesitation/stutering at constant speed until the check engine comes on, then all is fine. CEL code is 1 (oxygen sensor). There does not seem to be anything wrong with the wiring.
I am looking through ebay and found the ngk/ntk brand and bosch brand, and I remember seeing comments about certain o2 sensors that made the car run like crap even if the part was brand new so I would like to get peoples opinion on this,
Also, can my bad o2 sensor cause a fluctuating idle? idle goes up to 2000rpms for maybe half a second then drops back down and up again. I have cleaned the IACV thoroughly (wasn't very dirty) and I have bled the coolant, was just wondering if a bad o2 could cause this.
