I am having the same problem with a 2000 Dodge Stratus. After filling the
tank, the engine won't idle. If you attempt to stop with the car in gear,
the engine dies. There is also a strong gas smell, but no sign of spilled
gas. After it sits awhile, everything is fine. The Dodge dealership has
checked vehicle and found nothing wrong. Replaced fuel cap and fuel
filter. Problem still exists. Did you ever find the answer?
