after some spirited driving last night, I noticed that the car was a bit quiet then before. got home, check the cel and got 43. searched and found some thread where people fixed it by changing out the o2 sensor. I changed the o2 and left the ecu unplugged for the night before I cranked it up this morning and its still the same.

will be trying out my phearable h22 ecu after work and see if it makes a different.
