help plz !!

[Broken_down?]

I replaced the plugs and wires a few weeks ago and the truck was running so good I could not believe it. But now the engine is acting weird. When I give it gas @ idle it kinda spudders as it builds rpm's. I did not have the spark gap tool so I set them according to the old plugs. It was running great when I put the new plugs in... My bud said to check the timing. I do not have a timing light. I know you can set the timing by turning the distributer liek 5 degress. Plz help I need to leave to go upto the mountians in a 2 days. if there is anyone in Oroville or coming to oroville tomorrow and willing to give a young'n some help with his truck I woudl apperite it very much.

Thanks
Rich
