i purchased my 99 accord v6 coupe 6 months ago. and ive been noticing over the past few months that its been taking longer and longer to start the car. usually in colder weather. could this possible be the spark plugs? i thought the v6 99 had platinum tip that was made to last 105k? its only at 60...what else might be the problem? tell me what you think it might be and ill go ahead and check it. it makes a sound like vroom-vroom-vroom-vroooooooooommmmmmm START kinda hard to explain....

 

test your battery...

 

I would check the starter out too. Have it tested along with the battery. On my accord, when my starter was going bad, it would take serveral tries just to turn the engine over during colder months.
