Hey all,
Like the title states, the truck was cold and I was looking around the engine as it was warming up, decided to pull the oil cap and as soon as it cleared the last thread the idle dropped hard almost stalled. As soon as the cap was threaded back in it came back. Any idea on this? I've searched and found nothing.
Its a 94 1FZFE with 190,XXX miles.
