01 Silverado running rough.....SES light on


  

dave79 -> 01 Silverado running rough.....SES light on (12/2/2007 12:57:06 PM)

2001 Silverado 1500 5.3


Ok a few days ago my SES light came on and it started running somewhat rough. I already had new plugs and wires on hand so I put them in and the SES light went away and all was well, for one day anyway........  So this morning it starts doing the same thing again!  It smells a little gassy "fuel" under the hood.  I'm sure this could be about 50 differents thing but what could be the likely causes here?
