The arm connecting the rod linking the 2 banks to the spindle running through the throttle bodies? There's a grub screw holding the arm on and, on the 4.2 arrangement at least, it's on the underside. Maybe check that's not vibrated loose?
I didn't realise that.. Good shout ta. Nice and awkward to get to I am sure!
Winner.. Grub screw was loose.

So is it running as it should now?
Will find out later.. It was much better, but when I tightened the arm, it threw the bank balance out, I did tweak it based on TPS values, but not quite close enough. Tweaked it properly this morning, but raining currently.

Good news.

If you've the original throttle arm, it might be worth replacing with a threaded bar and some ball joint sockets.
Some made them using threaded bar and joint ends.

Or you can go better. You need 1 each of the 5mm ones CFF.00.05 and CFF.00.05LH

Model car's have reverse threaded turnbuckels such as

I have one - it's really good for setting up and maintaining the throttles.
Not a bad shout for a future mod.. My ends are getting a bit sticky to adjust.
