Message Need to look at Fuel Mixtures.. Widebands are good..

OR

Grab a ECU Talk, and Connector..

Look at your O2 Sensor voltage when it starts 'Falling Off'..

When you are 'In' the throttle, you should always have greater than .8 volt..

If the O2 Sensor Voltage falls below that you have a Mixture Problem..

You can also look at the Ignition Timing.. See what it's doing.. If it's pulling Timing.. LIKELY it's a Knock Retard..
