I took off the throttle body on my 85 duke and cleaned the passages out and the gunk buildup. Got it back on and the car runs great but now the idle is high, my tach isn't accurate so I don't know exactly how high but its about twice as high as it idled before. Car will go 15 mph in second with my foot off the gas. I don't see any vacuum hoses disconnected or leaking. Anyone have any ideas? Thanks
I guess I didn't wait long enough for the computer to adjust, just restarted it and it idles down now like before. It does have an exhaust sputter every few seconds, what causes that an exhaust leak?
The computer got used to opening the idle air valve a little more, to compensate for the reduced airflow. When you cleaned out the crud, you restored the airflow. So the ECM had to re-adjust.
That said, it's a good idea to reset the ECM when you do something like that to wipe the slate clean, so to speak. You may want to do that anyway, even though it seems to have re-adjusted.
As for the sporadic sputter, it's hard to tell without more info.
