'99 celica gt liftback 5sfe idle questions, a few questions... Options

[3sgteLuke]

hey everyone,

i just bought my celica with 66k 2 weeks ago and i love it. the only thing that annoys me is that the car has this ever so small shake. i cant tell for sure, but i would say my idle is between 700 and 800 which sounds about right. however, when i raise the rpms closer to 1000 the car runs sooo smooth i cant even tell its on. my questions are:

1 what should the idle be on the celica?

2 is there a way to adjust the idle? i.e. a TB screw? or cable tensioner? something like that?

3 do you think cleaning out the idle air control valve with TB cleaner is worth a shot? (tried it with last car and worked great)

the shake is nothing horrible but to be honest i love it when i know my engine is running perfectly. makes me feel warm and fuzy inside.

oh yea, i know these are pretty basic questions but im new to toyota, since i just switched from vw and i dont have a repair manual yet.

anyway, some advice and opinions would be awesome.
