If the revs are fluctuating when the AC kicks on and off, I would say that you have an issue with the ISC.

Have you checked the TPS?

ISC and TPS have been replaced with new ones, and I cleaned out the ISC holes it mounts to on the throttle body.

Or possibly the idle circuit in the ECU?

Mate the first thing you should have checked when you started the engine was manifold vacuum, a stock engine with good manifold vacuum would be around 20 inches of mercury and the map sensor would be sitting around 100htz, you have probably got around 12 inches and the map is sitting on 130htz and running rich. The idle speed control motor is probably chasing its tail, you have to learn how to check things , don't be a parts changer.

Only started doing it after I changed the injectors for the AU ones.

Just check to make sure it is connected or not damaged.

If you need, I have a couple of spares here.

When we put the AU motor in the Wagon, we used the wiring loom that was with it (EL Loom) but the original owner had cut off the plug for the air temp sensor and forgot to tell me. It was giving a bad idle and using excess fuel.

We soldered on a new one and it was perfect straight away.

Worth a check.

Maybe it just needs to be tuned, I've got a J3 sitting here doing nothing.

It shouldnt need to be tuned.. have you thought that there might be an issue with the injectors? ..
There could be a couple of lazy or internally leaking injectors..
You say they were exchange. Are they reco exchange. Bodgy home cleaned ebay specials or professionally reco flow matched injectors?

Reco injectors from Bursons, some AZNEW brand, on exchange basis, they cost about $600 for the set.

I've been trying to get new genuine AU ones out of Bosch but they've been on order for 6 months and no ETA for delivery.
