my 2003 tracker shakes at idle....and shakes when you come to a stop....i changed the motor mounts and trans mount...I also cleaned the idle control valve....any ideas

 

I was not aware you can clean an IAC? Have you cleaned the intake?

 

The EGR (exhaust gas recirculation) valve, if it's stuck open can cause the excessive shaking. I replaced plugs, IAC valve and mine still shook (1999 model). I have a new EGR valve to try next. I also have a 2003, and it doesn't shake but it idles faster. I may just increase the idle speed on the '99 and see if that helps.
