[tech/update]: fixed idle! and some observations...

[abatzis2@hotmail.com (Michael Abatzis)]

so i took off the idle valve today again--sure enough, nothing was moving in 
there. i realized that the electrical tests were probably working because it 
was a mechanical problem; the current was getting there and activating it, 
but the solenoid or whatever's in there didn't have enough juice to move the 
stuck valve.  a lot of carb cleaner went in, and i needed to work the valve 
a bit to free it (didn't do that last time, cause i didn't see what was 
supposed to be moving).  timed, set mixture, set idle, and for the first 
time since the engine swap, everything's within specs! woo hoo! also, 
noticed that my idle switch now works-- when i was trying to fix the problem 
before, i checked the switches. i noticed that the idle switch didn't seem 
to do anything; idle didn't change at all when the switch was on/off. now it 
does. i'm guessing that the ecu was trying to compensate for the stuck 
valve; hence the switch, and also probably why i couldn't adjust the duty 
cycle. wondering if this will affect the fuel economy (~20mpg city vs. 
~22-23 mpg with the 1.8). anyway, so i finally got everything working- now i 
can turn my attention to a new exhaust rattle. are these things ever 
*completely* problem free :) ?
