After driving my 1.9 , I began expericing shut downs while driving and sitting at lights. When I arrived at my detination, I checked the gas cap and noticed the rubber gasket was wet with gasoline. Is this a symptom that may speak to my stalling problems? YES, the gas cap was tightened; I always check it. And NO, I didn't put in any gas recently. Note: it is a locking gas cap (although I don't always lock it).
