I was driving home from work today and all of a sudden i got this message on my odom saying check fuel cap. havent got gas in 2 weeks so i guess it got loose from a bump or something. so i tightened it and it still had the message flashing. i checked the manual and it says it takes about 3 days for it to go off, i was wondering if anyone has experienced this before? if not i guess ill make a trip to the dealer in a few days. any info will help thanks in advance.
