shaking at idle

my friends accord shakes when you are stoped. but when you drive its fine. its a 92 accord. i was thinking maybe a motor mount or something.

could be a motor mount otherwise it might be runnning to rough or the idle speed is to low...

You know, mine was doing that also when I first got it. But I switched to using Premium gasoline, and I also use the EFI Cleaner or the Fuel System Cleaner. They help clean out your fuel injectors/whatever else, because I heard when you let your gas tank go below a quarter of a tank it starts picking up all those contaminates on the bottom of the tank which in return clogs your fuel injectors. Also another thing I notice in mine. I have A/C and when I have it on it'll drop the rpm's a little and I notice a little shaking but not much, just normal I think.

thanks for the fast replys.

You need to raise your idle. Thats whats causing the shaking...you need to adjust your either your IAC or your FIV.
