    I have a 97 F355 Spider with 19000 miles. I cant seem to get rid of the Check engine light. I have replaced all four O2 sensors, making sure they are the right ones. Then I replaced both ECU units. I have treated all connectors with that Stabuli???stuff. I have cleaned my Mass air flow sensor with the right cleaner. I have checked the air intake hoses for leaks,etc.. My air filters are clean. I do not have the original factory CATs, They were replaced by a previous owner a while back.
    My gas cap is tight. I have cleared the codes a few times and the light keeps coming back, roughly about 25 miles or so of driving.
    Does anyone have any other suggestions for me to do. I would really appreciate any input.

    Thank you

    Did you pull the codes to see exactly what was causing the CEL to come on? What code/s keep coming up?
