Ok, quick rundown.

Miles: 57000
Model: 2005 Base 2.4


Issue:

For about a year now it has idled at about 550 to 500 rpm. This occurred after a cold crank in cold weather the engine light came on and it began sputtering and shaking, after about 5 minutes and hardly a quarter mile (I was going to get it home and then look at it) it stopped sputtering and shaking and drove fine, just with the reduced idle rpm.
Lately it has been sitting at about 1000k after start-up until it has warmed up and then runs about 550 rpm again.
Of course a slightly sputtery and shaky idle does occur. All this began at about 43k miles
About two weeks ago it began hopping up to about 3rd or 4th gear before reaching 40 MPH and then acting normal...relatively. shifting down occurs at about 3k to about 2200 or 2500 and then slowly climbing again.
It is not a rough shift as i dont feel a lurch from the engine other than the standard shift.

I of course am getting worried about it as I am rather upside down on the loan and dont want to get screwed into being upside down on a car that is going to be a lemon because of the trannie.

Any help?

Oh, it has not had its 60k service yet.
