Plugs loading up?

[smtguy]

My car seems to start and run fairly normally. Miles are 182K currently. One thing I have not been able to figure out is when I am coasting downhill and get to the bottom, the engine wants to sputter like the plugs are loaded up or fouled. I am always able to clear it and it starts running normally again if I just hold the gas pedal steady (no pumping). Any ideas what may be causing this? The car does use some oil, but not a great deal, and other than the idle which is ok but could be smoother, it always starts and runs fine. Plugs were replaced a year ago by the previous owner. Maybe I need to pull them and take a look.

Anyone have any other ideas?

Thanks

You might have a quick look at the throttle position switch to ensure it is returning to the idle contact.

Good luck,
