My 740 runs fine until I depress the throttle at cruise, then stumbles. Haven't checked id the ECU is turning the ejectors off (as it does at max MAF signal) but the air/fuel meter (added) DOES NOT deflect lean. Very little written on this.
Have done a lot to check everything else...have not checked fuel pressure because O2 does not seem to show lean...

Have you checked fuel pressure and flow rate to injectors? Unless the fuel pump and fuel filter have been serviced/replaced you may be low on pressure or flow limited. Want to start a new thread for this issue?
