Posting your readings could help. Try some SeaFoam, put it into the brake booster hose. Are you running a 195 Tstat? My guess is that the check engine light is off.

i had the high hc happen when i had the Z26 but that was so long ago i really dont remember what i changed to fix it.
i think i changed the O2 and cleaned out the egr and its passages on the uim
