Plugs fail at higher RPM and high throttle openings when the actual CR is higher and therefor more compressed air/fuel between the plug gap making it harder to jump the gap.
Probably more like the MAP or airflow sensor not set correctly at the bottom RPM range.
Does it improve when the car warms ups ?
