Cold weather issues

Hi everyone,

We've had our Compass for a couple of weeks and have a few questions regarding cold weather issues. We've noticed that the engine generally runs a little rough until it warms up, is this pretty typical?

Secondly, it's only happened once but we had an odd thing happen this morning. At an intersection (after sitting for 3 minutes), I pressed down on the gas, and the car only idled forward (the RPMs didn't shoot up and was completely unresponsive to pressing the pedal), only to jump forward as the RPMs surged in the middle of the intersection.

I'm honestly not sure what to make of this. Any ideas?

Thanks

Any engine can run rough in the cold, although I haven't found that with mine. It's been down to -10 here in the peg some mornings already.

I've gotten that jerky feeling before in other vehicles before, usually indicating something wrong with a injector or the fuel delivery system. On your next fill put some premium gas in (although I know it'll kill on the $$) and see if that helps. If you have a Husky or Mohawk gas station near you go there to as the ethonol gas works as a gas line anti-freeze, plus the higher octane will help clean the engine. If it is some crap in the fuel line than that should help. If that doesn't take care of it then go talk to your dealer, could be a bad injector or fuel sensor.

I live in Florida, so we don't have extreme cold weather conditions here, but I have been having some problems with my Compass early in the morning when I'm on my way to work. The weather is only about 70-50 degrees (F), depending on the day, but within the first 10 minutes of driving (usually before I've even left my neighborhood) my Transmission Over Temp Light comes on, and my rpms jump to about 1000 more than they should be, with barely any acceleration.

Picture watching a film in slow motion, and that's how it moves. The light will cycle on and off for a few minutes, depending on how long I try to mainatain my speed; then when the engine temperature reaches normal, the problem stops.

I already brought it in once a couple of weeks ago when this happened, and they re-set the computer and said it was a sensor error. It's happened almost every day this week, so I'm bringing it in again, and will see what they say. When I called the service department, all they said was: "That's weird."

Also, after I brought it in, it's behaving more like a regular automatic than the new variable one.

Any ideas?

So far have not experienced much below 0C, but it's coming for sure.
You didn't mention the transmission you are working with but it sounds to me like something maybe associated to an automatic :
Can't imagine something like that with a real transmission :P .
That is, I meant to say, a standard tranny

I have the CRT and so far, the transmission issue hasn't repeated itself. I read of a similar issue some others were having over on a Dodge Caliber forum. I'm going to wait for the problem to reoccur before I get too concerned.

As for running a little rough in the cold, I'm chalking that over to me being hyper anal and trying to find fault where none exists :-)
