Odd cruise control problem Gen II

Good morning. 94 3.8, 118,000 miles. Out of the blue, CC started acting erratically. Upon engagement, car would surge and pick up about 5 mph, sometimes causing a downshift. Would not hold a steady speed, always seems to be slightly surging. It used to be smooth as silk. I don`t know if this was a coincidence or not, but the car suddenly died on me, and had to have towed home 10 MILES after this CC condition started. I found the solution to that right here, bad ground to the CCRM, causing it to buzz, and the fuel pump to constantly try to pressurize, and a no start condition. So I cut out the slightly melted ground connector, butt ended it, and also spliced in a wire directly from the 15 terminal wire, to body ground. Also noticed the FP regulator buzzing somewhat at startup, changed it. Car runs fine now, but same CC symptoms. No vacuum leaks that I can see or hear. Any ideas?

It was the CC servo. The CCRM controls the solenoids in that also, and must have taken them out as it was failing (voltage spike maybe?). A used Ford OEM CCRM ($46), rebuilt servo ($90), and the repair to the ground, solved all issues. I know there are not many of us still driving these Gen II`s, but hope this info helps others still who do.
