Finally have working IABs again
Did a bit of fault finding a couple of weeks back, and the Honda troubleshooting was pointing to the ecu. I tried fitting a replacement vacuum solenoid though, and that's done the trick even watched the arm move at high revs to double check it wasn't just placebo effect.
Think that's been knacked for a while to be honest, at least since the transplant. Great to have the old girl working like it should again.
Celebrated with polishing the rocker cover, giving the engine bay a bit of a clean, and a quick wash.
