I have had a code 1 flashing on my ecu for awhile now. Its getting old. I lose power the car stutters when the cel kicks after the car drives for about 5 mins. I have replaced the o2 sensor works for about 15 mins. then kicks it again. My mechanic told me that possibly because I have headers and an exhaust with no cat just a resonator and test pipe back to the muffler its not allowing the o2 sensor to heat up enough causing it to kick. Anyone have any suggestions its upsetting when I lose power.
