I'll have to take a look at the throttle linkage. I haven't done the cruise control amp yet as I am relatively new to these vehicles and afraid to tear things too far apart.

We generally have a shop so most of the mechanical work for us due to a lack of mechanical experience and time on my end. just have the skill set to replace capacitors and find bad solder joints.


Not cruise amp - the cruise actuator. On mine it was much stiffer and it affected the dynamic return, and actually held the rack allowing overshoot upwards too.

See this video which was an example:

But it would also allow an undershoot as well. Yet you can see that in other cases, the ELR allowed a soft landing.

Interestingly that looks very similar to what mine is doing. It'll start up and idle right where I want it but then after revving it'll land wherever it wants. Though mine also still likes to come down below 530 and come back up to where it's supposed to be. May have to take a video at some point.
