First post! Can anyone please ID these square, black, plug/wire collectors for me? They mount to the top of the motor, toward the back, above the rear spark plugs:
Earlier today, upon start the check engine light came on flashing, engine ran rough. Popped the plastic engine cover to check coil packs and noticed one of these things was just hanging there, not slid onto the motor. Reattached, disconnected the battery to clear the code, and it runs smoothly.
Coincidence? What are these?
