What have you done to the vehicle so far ? I'd suggest doing a few things to even out the idle....like Like - Cap, Rotor, Plugs, Wires, PCV, Air Cleaner, Fuel Filter, sea foam in gas for starters..... Next could be, I suspect Timing, EGR cleaning.... I have a newer blazer (99) so the timing is always set by the computer...but these are things I'd start with....

Re: shaking while at idle
Isn't the harmonic balancer supposed to keep the shaking down at idleing? Just asking.

Re: shaking while at idle
Have you checked your CPI and nut kit? Might be starving a little fuel (enough to shake, though with your idle steady I'm not sure about that) Also take a look at your motor mounts. The may be farked and it's allowing the rocking in your motor.

So...how many miles on the truck ?... When you did a "Full Tune up" what does that mean exactly...... Did you change the wire sets.....maybe you have a bad wire....without knowing what you did in your tune up we are only guessing...so tell us more !!!!

Re: shaking while at idle
183000 miles. that could be why. wires, plugs, rotor, cap, fuel filter, oil change(mobil 1), oil filter, air filter, 02 sensors. everything and anything. it isnt that bad of a shake, just a little tremble. not too bad that i will go off and spend 500 bucks to fix. thanks anyway everyone.
