Cruise Control 300E
When I first bought the car, cruise worked, but never really used it. Then I didn't use it for a LONG time, and tried it. It was constantly shifting up/down and not maintaining speed. I replaced the cruise control amplifier with one from another 1991 300E. Now it works, but there is an ever so slight rpm fluctuation up and down (50rpm) that you can feel when cruise is engaged. It just feels wrong! It works great otherwise if you can get past the weird pulsing of RPMs.
Does it sound like possible solder contact issues with the used replacement too? Just not bad enough to totally fubar the cruise system....?
