G6/2.0L Runs after key removed
My 2007 G6 4 cyl continues to run for 3 to 6 seconds after the ignition is turned off and the key removed. Aside from the timing of the engine shut-off, nothing else seems amiss. It just runs for a bit and the accelerator will rev the engine. When it shuts off, it doesn't do anything like shudder or shake. No engine light or anything. The car runs normally other than this.
This is consistent. Once it did start hard recently, then when it started the 'check airbag' light came on. This happened only once.
