Took my car for a ride. I noticed hesitations. It does not seem to be misfire. The hesitations appear only around 2500 rpm when I am at a constant speed and give slightly more gas to accelerate very gently.
A CEL code 2 appeared and desappeared the next time I started the car. The car ran perfect when the CEL whas on (default mode ?) and hesitated again with no CEL.
I am leaning toward a wrong O2 sensor as the car ran well on default mode. Can you confirm ?
Should I confirm that by pulling the O2 connector and drive with the CEL on to see the hesitations disappear ?
