Linkage rod from cruise control to injection pump throttle causing high rpm til warm
 

Mine is plastic at both ends. I cleaned it & used silicone grease to lube it but the plastic ends still grab the ball a little too tightly ( until the engine warms up). As others have commented this will sometimes cause the rpms to be excessive.

What have any of you'll done to minimize or prevent this?

I have ordered a new linkage rod that has to be shipped in from Germany ( about $35 ). Part # is: 0 001-070-85-75 rod throttle through Plano Dallas Mercedes

Is there a linkage kit available so different length rods can be made? I've searched the internet without success.

I'm in the middle of about a 3-4 week work effort to:

1. replace glow plug wiring harness
2. replace delivery valve o-rings & copper washers
3. clean intake manifold
4. replumb engine vapors & oil to a catch can instead of intake manifold
5. replace alternator pulley with gates 37011p ( might need 96 alternator, don't know yet )
6. replace front flex disc
7. replace shifter lower plastic bushings
8. replace motor mounts
9. pull monowiper assembly to clean & lube
10. pull blower motor to clean & maybe replace brushes
11. replace belt shock reducer
12. try to figure out why both front windows don't move
13. try to wire in a bluetooth adapter so I can play music from my phone

So far everything has been easy:), just takes the time & lots of searching to get guidance on how to do the work. I think my car was built about May of 95 so some older car pictures are close but not the same.

I've taken a few pictures & will take more if any of you have an interest in what things look like. PM me is ok.

Grease is too thick. Take it apart again, clean out all the grease, and live it only with a few drops of ATF.

Go to a junk yard surely you can find a gasser or diesel with the metal ends that you can alter to fit. I would have some if you wanted to PM me but this time of year shipping may take forever.
