found this - they seem pretty important and could def be what is causing idle issues
with mine, its not as much tht the idle bounces around i think i fixed that a year ago - but now its just like every now ant then its choking or starving for air of gas - the rpm never go up just down (last time they would bounce back and forth from 500 to 2000) - but 98% of the time its at 750 and idles perfect
