help! i think i broke it

[David]

I had the same bucking problem on my 87.5 CGT (NG engine also). In my case, the hall sensor had partly pulled out of the distributor. The feet were broken and it slipped out. it is now secured with a wire tie strap.

Same thing happened to one of my cars about 5 years ago(1986 4000csq.) Very 
disturbing.

I messed with everything under the hood trying to get it to return to normal.

I finally got the bucking to mitigate but not totally go away by changing 
the spark plug gap to 45/1000.  The next week, I discovered that I could 
get the bucking to clear up by changing the spark advance about 2 degrees 
outside the book specifications.

I don't recall if it was clockwise or counterclockwise.

After the spark adjustment, I regapped the plugs to normal and the bucking 
stayed gone.
