This morning was the coldest morning thus far at a whopping -27 degrees. I went outside to turn my '8 on to let it warm up and it just sounded and was running horrible, I had never herd a car sound like this. It was almost as if the rotor was having troubles turning, THUB THUB THUB. My '8 only has 2600 kms and is only 1 month old. Has anyone else who lives in the extream cold experenceing this? Please let me know so I know weather or not to go and have it checked out. Thanx

it was like 2 degrees where I was the other day and it was pretty harsh to start it. it was reving it self to like 5k rpms. after like 20 minutes all was good.

I'm sorry I can't be of help but I'd check the Canada section in the Regional forum. They do have a lot of helpful advice and should be able to share with similar experiences. From what I've read, the 8 IS slow to warm up.

it was 5 degrees F (or about -16 C) this morning and my car started kind of hard (almost like I have a weak battery) but i really didn't notice any significant weird noises.

Any car is going to have trouble starting and sound differnt in that cold of weather.

Car started a little rough but not too slow. It was making a weird noise from the right side while warming-up, some wierd ticking that followed the RPM. All became normal after fully warm though. I am thinking to use premix for extra lubrication in these temps....

thought about starting mine up today, but then realized it would be a pain, so i used the ttc to get to work.

Heh... cold start threads popping up like crazy with this cold front, anyway...
I started mine this morning when it was about 5 degrees F out. It definately ran rough... I think this is normal though for rotaries, i know my Dad's 88 rx-7 used to sound like a cat with a hairball warming up in the cold. What I am surprised about though is that the rx8 doesn't seem to warm up as well. That '88 would pin the tach well over 2 grand iirc and not come down till it was pretty warm. The 8s barely go above 2 grand and come down to about 1.5 almost immediately.

To help the warm-up this morning I held the throttle steady around 3k. The actual RPM was jumping around +/- about 300 rpm while I did this... so I held it till it was smooth (about a minute). I figure that's good enough to get goin.. I'm definately not gonna put load on it if its running that rough, but once smooth I'd say its got the fluids flowing and enough parts up to temp to not harm anything.

Maybe the dropping of the idle is related to the PCM flash so the car doesn't flood easily. Just a thought. Also mine generally stays at 2+ for a while before dropping.

I find the RPM's in my 8 cycle in cold weather. It starts by reving from 2.5k to 3k. This continues for about half a minute or less. Then it repeats the cycle at a lower RPM. It almost seems like it's programed to respond in that manner. Whenever this happens I let my car warm up for a good 10 to 15 minutes before driving, or at least until the rev's come down to 1k.
