Hi there,
I had to tow my 80 Series home today. Right at the start of a small climb, it suddenly lost power, and smoke started coming from under the bonnet—definitely from the airbox. The engine would still start, but when I tried to rev it using the accelerator cable in the engine bay, it would lose power when revved hard.
After towing it home, I had a closer look and found a loose cable connected to the ignition coil. I’ve reconnected it, and now I can rev it hard in neutral using either the accelerator pedal or the cable in the engine bay, and it idles well too.

Could a loose ignition coil cable have caused this issue? Just want to make sure before I go for test drive.

Thank you.
