Well I changed all my spark plugs and now it seems to be fine, it has less than a half a tank and it does not do it so I think it is in the electrical sys. i bought some autolite plugs. When i was changing the plugs I found that cylinder #3 wire had a gash in it. I glued it and wrapped it in electrical tape for a temporary fix. I am getting new plug wires tommorow. and I am going ahead and replacing my o2s.
