there is a mechanical activation of the Idle linkage in a link on the left side of the TB but most of the idle speed is set thru the ecm control of the injectors -- I think... I'll have to double check that.After spending a lot of time with this thing I would expect the stv's to act much like a choke...close, open, then almost close. I think that's where the fast idle gets set. I may be wrong.
It is mechanically set for fast idle but if you move the throttle, I think that it drops off the step.I noticed that when I manually close the stv's that puts the fast idle screw on the higher step of the mechanical linkage. Then upon returning to the running position the tb is set for fast idle when started. Right?
That eastern rust 'll kill ya.... :biglaugh:Viper and so the rest of u know. I was having issues with my FI. it first started it in the spring checked it all out it work fine in till following spring it did it again. i live in the north east and what was happening was just a miniscule amount of rust was forming and when i would disconnect the wires look at them and plug them back in it would clean them and cause no problems untill it set for winter. a little dielectric grease solved all my problems
What manual do you have?I haven't checked the IAP's or the intakes air temp sensor but I have chk'd all the rest. It really blew me away when the new ECM didn't correct it.
Soapball, I have chk'd all the connections and they are clean. One day it was fine and the next it wasn't.
Q's for when you're rested...Thanks for now you guys, I'm going to sleep on it. Tomorrow's a new day.
I read that theory about stripping the gears by manually moving the STV's too and was cautious because of that but after looking inside the actuator it is obvious that the gears are not fragile.I did not know you could move those valves (butterflies) manually.
I was always told that moving them manually would strip the plastic gears inside.
Is that not so?
My problem was on a bike I was rebuilding from a hard hit, it knocked that solder connection loose. I was able to find a STP sensor for sale on e-bay (a guy was parting out a throttle body). Mine was off a GSXR.
I'm wondering if moving the butterflies manual may have got the gears "out of sync" if that makes any sense, so that when you are setting the position according to your multi meter your not getting an accurate setting.
My problem was 6 years ago so my memory is alittle foggy.
