I got gas a while back and just down the road car started missing and could barely run, limped it to the house to remove gas from tank finding some water, changed filter and haven't got gas from that station since. Car ran fine a couple of trips out and started stumbling again just the other day. I changed filter last night, drove car tonight and after about 7-8 miles car started missing. Could this possibly be coil pack, plugs, or wires instead of a gas/water issue? Didn't really see any water in filter taken out last night.
