Blipping throttle prior to engine shutoff

Hi guys,

I have developed this habit of blipping my throttle slightly (anywhere
from 500-1000 rpm above idle) and then shutting the engine off
immediately before the revs have a chance to drop.

I have noticed that my car is much easier to start. Should I have any
reason to believe this is damaging to the engine? (B16A3)

yes. unburnt fuel dilutes the oil film on the cylinder wall.

 

that is a very interesting point. thank you for the reply, i hadn't
thought of that. do you mind going into detail a little? Since the
camshaft continues to spin momentarily even though ignition was turned
off, wouldn't that mean that my valves continue to open and close
thereby venting the air/fuel mixture?

 

I would buy that argument on an older carburated model but not a newer fuel
injected car where emmissions are very low even on deceleration such as a
throttle blip. This low emmission engine would not be putting any
significant amount of fuel into the cylinders.

FYI I see no correlation between what you describe and an easier start when
you get in next time. The only thing that I can think of that would have
any effect is fuel pressure but that would be holding steady pretty much the
same no matter what you did prior to shutoff. I think this is in your head.

Time it with a stopwatch next time.

Don't worry, you'll outgrow it.

I HAD to do that on an old junker VOLVO, or it wouldn't shut OFF, but in
your case, If it was starting poorly, maybe you just need to run a can
of Techron fuel injector cleaner through it?

Read the part in your manual that describes 'cold weather / high
altitude /flooding' Our Odyssey had an injector sticking open, and
starting in the AM was terrible until we figured it was flooding overnight.
