Is your check engine light on? If so this may help you in further diagnostics. Let me know and if possible get a code from the light so I can further assist you.

2003 trailblazer trembles when on Drive but stopped, stops trembling when i put it in Neutral. How do i fix this problem


some times this is caused by high engine idle, or there may be an issue with your transmission, i would start by adjusting the idle, "lowering it" you can find the correct procedure for this and the right rpm range for the car in gear, in most manuals

AC blow out hot at low rpm


when you are stoped does the car idle fine. when the rpms are low the compressor does not get the pressure up high enough. you may need to get you idel turned up a little or your vaccume advance may have a vaccume leak.
