Misfire except when WOT

[damastah]

Searching only shows results for misfire at WOT.

But I have the opposite. It does not misfire when full throttle.

But it does have an idle misfire and 1%-99% throttle misfire.

Has anyone had this?

Idle and POT use the O2 sensor, while WOT ignores O2 sensor data.

Perhaps your O2 sensor is bad, and giving incorrect readings to the ECU? Try unplugging it.
