What 'actual' symptoms do you have other than the codes?

Car starts and idles fine, will drive perfectly OK until any load is applied (anything other than VERY gentle throttle) - car then shows Restricted Performance message. goes into limp mode. I found that switching cruise control on to get the car home at 50mph didn't bring up the fault.

Your diagnostic tool doesn't recognise the injectors, not that the ECM doesn't recognise the injectors.

They can be replaced without removing the doughnut “plenum”, but you may wish to clean it out a bit at the same time.

clean as much as you can as Mike says, consider doing the throttle body too.
