Default Cold winter morning...

...I noticed in the morning when I start my car that it starts up/idles rough...but after a few miles (everything circulates) its fine...is it time for winter maintenance...if so, what's on top of everyone's list???

Thanks for the tip(s),

Do you let the car warm up at all? You don't need to wait 5 minutes ... but I always give my car at least 30 second of idle in the morning. sometimes about 2 minutes if it is cold.

If I don't let it warm up, just start and go, it makes a clicking sound for about a minute. Kinda strange

When you start your car, does the choke hold the RPM at about 1500? maybe your choke isn't working for some reason, and the car is struggling with the low idle speed of most of our subies.

The cold is back. You may consider some service for car if due by miles. FYI I have a 2000 RS and have only been trough one winter with it but two things that happened last year when it was cold out. First thing I noticed that the car like yours will run rough and hunt for idel speed when firts started. Then (most likly when it gose into closed loop) after a shot time it idels up alittle and runs fine. The other thing that happened twice both on VeryVERY cold Michigan mornigs, my car stalled almost imediately after start up. It had less that 4000 miles at the time and I attribute it to the extremly cold temprature that the enigen managment system dose not understand. However this summer I did remove a spark plug to see what they looked like. When I saw they were Champion brand I quickly discarded them and installed some NGK's. My experience has shown that Jap cars run really good on NGK's, German cars run really good on Bosch plugs, and lawn mowers will run on Champions. Since I replaced the plugs my car idels smooother all the time not just in the cold. Just my $0.02 hope I didnt bore you.

I switch to 5w-30 Mobil 1 during the winter. I don't live in cold weather but I drive up to the local ski area all the time. I always like to warm up my engine and let the fluid circulate. As far as winterizing your car goes, change wiper fluid to the deicing kind, make sure you have enough coolant/antifreeze( change it if you haven't in 2 years) Changing plugs isn't part of it, but it always helps. Also, you might want to get an engine warmer if you live in a particularly cold area. Oh yeah, check your battery. You can check your hoses also, but since you have newer car, it probably won't be an issue.

Well, since you're having a cold start idling condition, I would check/replace plugs, wires, and filters if you haven't done those. Also, clean the battery terminals.

A CHOKE? LMFAO! your car most deifinantly does not have a choke... those went out about the same time Jimmy Hoffa did...
seriously though, fuel injected cars do not have chokes, and the idle speed on your Sub is controlled directly by the pcm. still LMFAO
