Hi all,
I have a 1959 TR3A.
Based on an idle that has a mind of its own where it can go from 1200 rpm down to about 600 or vice-versa with the tap of the gas pedal, is there a quick and dirty test that I can do to check the sanctity of my throttle shaft? I have a vague recollection that this is something that can cause tiny vacuum leaks that can in turn cause strange idling problems. My main problem is that sometimes, especially when I have not fully warmed up, I will come to a stop sign and the rpm's will fall until very close to stalling or actually stalling. Then my heart starts racing and I have to take a crank or two away from my starters life. I have really explored the mechanical aspect of this and do not see that I have any play there though if anyone could point out a likely suspect in the linkage I would like to know about that.
Would it be useful to spray oil on the throttle shaft while running to see if it changes rpms? I think that I have done that and did not hear a change. I guess I am kind of stuck on the 'throttle shaft vacuum leak' theory right now.
Thanks very much,
Jim Lee
