is that normal or no? its at like 1100-1200 rpms, is that bad?

I agree, every 4 cylinder I have ever driven has always idled @ around 1100 rpm's.

I see it bounce around between 690 and 710 usually (digital gauges). ... if the compressor (A/C or windshield) or anther load is on, the idle will be around 800, maybe as high as 850. I don't know what effect underdrive pulleys would have on the idle, but I think the ecu would compensate.
If you're not idling at these rpm's, there's something else going on that is making it abnormal - egr valve maybe, vacuum leak, glogged air or fuel filter, bad O2 sensor maybe(?) ...
EDIT: there's no way that installing a motor mount would do anything at all to your idle, unless you bumped something else in the process. Did you install it from below? If you installed it from above you might have bumped the O2 wires.

doesn't it shake like hell? I know that around 700-750 my exhaust is almost hitting the bumper it's shaking so much and the shift knob is a blurChopstickHero said:after installing my injen and turbohoses smic/hardpipes kit, my idle dropped from about 700rpm to about 500-600rpm. it doesn't bounce up and down much, just sits there.
