'87 bucks & jerks at lower speeds
Hello everyone,
I need to know where to start my diagnosis.The '87 runs great at higher speeds.It starts right up and idles fine.At slower speeds (30-45) it bucks and jerks.As soon as I resume higher speeds it again runs fine.
I have the FSM,I just don't know where to focus
.
Have any of you guys/girls with '87's had similar problems?
Thanks in advance for any help offered.(Please don't tell me to search
),I have.

Did you post this in tech before?
Did you rule out your TC lock cycling? That is normally what you are feeling with an auto with 2.59s
