I have codes reading that I have a throttle sensor problem, and unpower problem on 2006 Saab 9-7x

Throttle sensor reading indicates problem and when light comes
on I can barely pull a hill. Sometimes in warmer weather all the warning lights go off and it runs regular. When it is cold
outside it does not run. I need to get a picture so I can see if if I can replace 1 part at least
