The prankster almost got us.
Yesterday the oil pressure gauge started to vary as if the engine was packing up. Very low at idle and up again when driving. And then suddenly low again while turning a corner.
Nothing seemed wrong with the engine, but it was a bit unsettling. Everything seemed fine in the engine bay.
Another test drive and it seemed fine until it happened again. Then I found this wonky connector on the sensor hidden in the sleeve. Easy fix.
