2001 MPV LX SPARK PLUG REPLACEMENT
 

All:

Any suggestions on how to remove & replace spark plugs in my 2001 MPV LX (mileage: 56K)?
Miles per gal have recently averaged 14-15 mi.
Also, gas pedal seems to get stuckafter your first depress the pedalafter starting...was told that throttle body/intake manifold has carbon build-up. Any suggestions on how to fix?
Will appreciate any help/suggestions/and or diagram on how to do both.

Thanks.
