3. What pressure???

Besides what do you think happens when you park your car and turn the key to the off position??? I do exactly the same thing except I do it while driving...
1. Perhaps on your engine... mine sure doesn't (ditto my last car) And that's weird you SG goes dead - I'll add that to the list of reasons I'd prefer not to go that route (my SG stays live with spark cut)
2. emissions
3. pressure: colloquial for vacuum pressure

When I turn my key off - my ECU cuts fuel and spark, some solenoids close etc...

RH77 got it spot on
