1997 Chevrolet Cheyenne

Hi guys,
I have a 1997 Chevrolet k2500 4x4 with a vortec 350. It seems to have a noticeable snap in what sounds like the distributor at higher rpm levels.I pulled plug wires off and the number 6 plug wire that runs to distributor cap was corroded white. So I replaced with a used one I had laying around and it seemed to fix it, for awhile. Now it is doing it again.I switched wire around 2 months ago and it started missing about a week after. This is getting kind of frustrating!Any help would be very much appreciated. Thanks

Change your wires and make sure the fireing order is correct also check your cap and rotor for corossion and replace as needed same goes for your spark plugs

good luck
