So, that's rich. What happens when you turn out the CO screw?? Remember,
you must set up things per Bentley to do the adjustment. Disconnect the
idle control and plug the leads together. Disconnect the
temp sensor. Pull the crankcase breather hose and plug the hole in the
intake duct. Disconnect the oxy. Verify with Bentley cause there may be
something else I've missed.

The swing is larger than normal, but it does show the oxy is responding
correctly and talking to the ECU. Follow open loop adjustment procedure and
get a setting as close to 0.5 volt as possible. Then hook up everything and
check the closed loop flux again.

A visual test of spray pattern is all you need to confirm. Replace any not
giving a fine mist.

That always needs to be verified first, then timing and only then fuel delivery.
