S10 (T10) 4x4 p/u OBDII codes

I have a '96 Chev T10 4x4 p/u with 4.3 L eng that's storing a P0700 code which normally would refer to the TCM for an automatic transmission but mine's a stick shift...! What does this mean...? It also stores a P1192 code which is GM specific as "post-catalytic fuel trim system bank 1," I think. Any ideas on either of these and are they related somehow... (?)
