Angry Sputtering and rough idle in the cold? EEK!

So today I start my car after a long day of work, and my car is sputtering and idling like an old Hyundai Pony.

It was pretty cold today, like -12C, but its been colder, and it hasnt done this (actually, once, but not this bad!).

It took a few turns to start, then it idled at like 1500 rpm, sputtering the whole time! I waited a few mins to let it warm up a bit and drove off. Man, it was REALLY screwed! It didnt wanna move under its own power, and when I took my foot off the gas, the idle would go down to almost 100rpm!!! The drive home wasnt any better, felt like it was running on 2cyl. Finally, after about of 15-20 mins of driving (an WELL warmed up), I gave it a bit of gas to clear the engine and it started to work normally again.

What the HELL was that all about? I mean, its gotta have something to do with the cold. Is it because of my longish start? I mean, I turned the engine over for a WHILE before it started up...maybe I "Semi-flooded" the engine and it was running rich or something....does that make sense?

Whats the best way to start the engine when cold? Cause I hate crankin the thing when it doesnt wanna start...should I just crank the engine, and stop, then try again...or one long crank?

I have NO idea, actually.. (<--embarassed face). I got it changed at the dealer in November. I would have to assume that the dealer is smart enough to put in some 0 weight for the winter...I mean, its not like its your ordinary, run of the mill know nothing dealership either, so they HAVE to know!

But still, how would the oil affect the engine even after it was warmed up? It was still sputtering when it was warm!

It was perfectly fine today, and it is still as cold as it was yesterday...

heavy weight oil would could cause a long crank, I was just curioius, wouldnt have anything to do with the sputtering.

has the problem happened again?.

did the cel come on at all?

sounds like it could have been some moisture in the gas.

Ok, no prob...

Nope, no CEL!! It has happened ONCE before, but near the beginning of winter, on the first COLD day of the season. Sice then, the weather has been up and dow, but it has been MUCH colder that it was both times its happened...and I've had no problems....

it is possible what you say about the fuel, since I just filled up the day before it happened...hmmmm.....

Hey Goose,

Maybe you already know this, during the winter make sure you run on the top half of the tank. Reason being is, condensation can build up and clog vital arteries within the engine until the thing warms up.

Specially if you have a heated garage. Sounds like a case of moistrure getting stuck up where it shouldn't be.

Or it could be just bad luck...

Oh well...
