Engine stops oddly.
so i have nmoticed that when i turn my car off the engine keeps turning and it sounds like it rotates a couple of times after the explosions stop.
What could be causing this?
I put 91 octane in the car.

Do you mean it's "dieseling"? (like running on) If that's the case after you put in 91 octane could be a carbon build up causing pre-ignition. When was last plug change? Does it do it everytime you turn it off or only after certain circumstances? (more info please) |

yes dieseling if thats what u call it.
Changed plugs about 15-20k ago. New wires also. Bosch all around.
Usually only does it when its hot, when i take a drive longer then an hour or when i drive spritedly.

Run a bottle of Techron or STP gas treatment and fill up tank at same time - see if that helps. It sounds suspiciously like bad fuel and/ or moisture in gas |
