4 days ago I was out of town and spotted some cheap gas and I think that is just what I got. I filled up and the next morning my lumina was missing pretty bad. I put new plugs and wires and new fuel filter and have run gas treatment and water remover in two tanks of gas. While the car is running much better, It still lacks power going up hills and just kind of bogs down. When I am stopped the car just shuts off unless I keep my foot on the gas. Any help would be great. By the way, my lumina is a '92' 3.1 v6 with 215,000 miles.
