Engine misfires under medium and full load, and sometimes under steady conditions.
Advance and KR behaves strange.
Could it be a sensor fault?

Also post your tune file.
What engine mods...?
Std tune. Cleaned main terminals on battery and main grounds. Also cleaned connectord to Pcm.
Checked for leaks on manifold - none. Also coil #5 was misfiring periodically under load.
I think a bad ground connection caused the 45 deg retard on ignition.
The bad coil also really made it cough and perform bad. It's ok now, only a few occational high rpm misfires on first gear
@wot. Possibly the plugs
