i am having an idle problem when i come out to my car from the store and start it up after it's kinda hot. it will idle very rough and sound like it has a cam. it stays rough while i back out of my parking space. as soon as i hit the gas to go forward it smooths back out and continues to run fine. cold starts are fine and i just did motor mounts. could altitude have anything to do with it? as i moved from NY to NM about a 5,000 ft. elevation increase. any ideas greatly appreciated.
 
Any codes.....

Yes altitude could effect it but it should adjust these SC eecs are very sensitive changes do effect how they run.. Cooling of 15 to 20 degrees can make a big difference.... Some times when it is cold out I will run my codes and get ECT and ACT out of test range because they are touching cold steel as soon as car warms up codes go away.. It was probably just a little lean and needed some gas and fuel pressure.. I would check for codes if there are no codes I wouldn't wory about it....
