Hello i have a question to all you experts out there. Usually when i start up my 02 millenia i have to hold the key down a little extra than normal or else it wont start. It dosnt make any crazy noises or anything like that, i was thinking that maybe it might be the spark plug but i dont know too much about that stuff. Any suggestions from anyone?

What is the milage of your vehicle and do you have it serviced at the dealer?

Does it have a Miller Cycle engine?
