1987-88 manual..section G pg7..shows speed sensor as input to pcm with others..
Crank sensor..is move able and I seen a jumper mentioned..
Its just something...
The isa motor. Was making clicking but it stopped..also before it would make a grinding gear sound after you turn off engine..that stopped also with just with sensor..
Just more to check out slowing
Test drive lastnite was about 25 miles..vs around block..
It has larger tires so speedo is off..it held 50-60 no problem..
