on top of the vacuum leak in the intake boot, i think that my throttle plate may be sticking. by that i mean it is not rasing at idle. i had to raise the idle alot and it was pretty tough. what is the size for the idle screw on the CIS? its 3mm correct? anyway, needs a tune up badly. next paycheck i should be able to afford some stuff, so get ready ubernugen, in two weeks the 90 is gettin a tune up!
