Shakes or Wobbles problem
2003 Chevy Trailblazer 6 cyl Two Wheel Drive Automatic 133K miles

Hello:
My Trailblazer idle is bad when the AC is on. When the AC is off it feels a little better. I change the spark plugs, air filter, better gas and gas additives but no luck. It feels like you are getting a massage. Also I have this tic tic tic tic tic noise that only goes away when I give gas. Can anyone help please. Thanks.
