A9M computer

[1991vert]

well i just looked at my passenger side door and saw an "A9M" sticker so i took off the kick panel, and further saw that indeed, it was an A9M computer.

i always here able A9L's and such, but how common is it to have an A9M? was it switched in?

car is a 1991 mustang convertible 5-spd. i thought there were only 2 computers for the mustang, A9L and A9P?

car sometimes has a hanging idle and seems to stick when i shift gears. could be the throttle cable though.

any responses would be great

thanks
Chris

if my memory is correct, the M puter has some very nice timing tables.
