Lihtan geo service manual

still trying to fix my problem. Found LIHTAN"s copy of the 1992 factory service manual. For 1.0 motor vin6. on the site. How much different is the 1990 1.0 motor? How much trouble will i get into, if i follow the 92 specs, for the 90?
Thank ya.

Mechanically, there's no difference at all. Wiring, sensors, and controls there are slight differences.

Woodie, Great!, at least i got great factory info. that could , or could not help. to some degree. Thanks a bunch.
