@Leon771, with a loss of one injector, power will be down 1/8 since only 1/8 of the motor is working So that would mean 266kw instead of 305kw (for a standard engine). 266kw is more than ample on a public road so that you won’t need to push the accelerator appreciably more than is normally the case. As such fuel use shouldn’t change much. But the engine will be a little rough. The more failed injectors you have, the rougher it will be and the more power you’ll loose.
If it was me, I’d measure the injector resistance as it’s is an easy way to determine if an injector is foobared. Surprised RACV didn’t do this simple diagnostic check, guess computers know better.
I think the standard injector resistance is 14 Ohms. Anything outside standard resistance or a large difference between all injectors indicates a problem. If it’s a failed injector, as you have an injector DTC then the Holden selling dealer should be footing the repair bill in replacing all 8 injectors under your factory warranty or ACL statutory warranty if you are out of factory warranty.
If you bought the car privately, no ACL warranty applies and if the factory warranty has expired then you’re out of luck and on your own.
No idea whether a failed injector would be the cause a P0102 MAF circuit A fault… I don’t think so… Maybe the connector is a little loose due to the engine vibrations so unplug and replay the MAF connector and check the sensor voltage and ground are ok…
