If you don't drive the car much, you may have condensation in the gas, which causes poor running. Also, gas can go bad or "sour" after a few months. If you think this is the case, there is a drain on the bottom of the fuel tank which you can loosen with a large pair of channel-lock pliers. It is a large hole, so be aware that all of the gas will come out fast. Another item that may be the cause of your problem is the fuel filter. If it isn't new, replace it. These older cars like ours can have a lot of contaminants in the fuel, and the fuel injection system needs to be kept clean. Also, a bottle of Techron in the fuel (from your local Chevron station) can do wonders to clean dirty injectors. Beyond this, you need a set of fuel pressure gauges to troubleshoot the problem. Hope this helps, Bob at Pelican Parts
