Hi CL:
My 99 ES300 has 145K is kept in immaculate condition. I've noticed now in cold weather the car takes longer to start, spending more time cranking (like 1.5-2 sec). Could this be sign of something going bad?

I checked the battery (less than 1yr old) and terminals, all look good. Anyone else experience this?

Thank you!

Maybe sticky or leaky fuel injectors....
Try using some fuel injector cleaner.

In extreme cold weather, I've seen all cars do that. My ES does it, my old Nissan did it, my old Ford did it... So I wouldn't think there is anything wrong.

its normal, thats why companies recommend you getting a good battery during the cold winter months.

batteries are rated in cranking amps (CA) and cold cranking amps (CCA). cranking amps is how much power the battery can exert above freezing, CCAs are amps that can be output through the battery below freezing. (it may be 0 degrees, i'm not sure) more amps = more power exerted, and since CCAs are lower that CAs always, it will put out less amps/power at lower tempurature. this is also explained by electrons are excited when warm, and slowed down when cold. hope this answers your question.
