passed smog
 

here it is: c.o% @ 2500 RPM is excessive. idles rough-HC levels are too high at idle. no vacuum to egr. any ideas ????

RE: failed smog
 

Carb or fuel injected? Mileage on vehicle? Any new parts?

Incomplete combustion (bad plugs/wires/dist cap/rotor), carbon build-up (high mileage), poor tuning, etc can all lead to high exhaust emissions.

Kind of tough to give any help with the limited info given.

rebuilt 2.2 carb. 200. miles on rebuild, 177.000 on truck itself. new plugs/wires new cap/rotor, new fuel/air filters, i think it's in limp mode, the vacuum solenoid valvefor the duty valve that opens the EGR valve is not getting 12 volts to open the valve. how do you get it out of limp mode ?? Thank You.

Sounds like you got it all squared away....I hated CA emissions tests...none of that crap here in MI.
