Happy 2005 to everyone! I finally get a chance to share the outcome of my troubles. Yogi 123rd is the winner. I followed your suggestion and visited Autozone and bingo! The code revealed that it was one of the spark plugs cable. I know I know guys...I sound stupid for not having checked that first but I know little about cars. Isn't it obvious by now? Anyway, thank you for all your helpful responses and I wish you a wonderful 2005 from sunny Miami.
