Not Passing emission's :-(

Hey Guys and Gals, First I should say that I have a 1991 Toyota Cressida with the 7MGE motor and since I really can't find Cressida forums I come here for your help. I just recently had to do a head gasket on the motor and am trying to get it to pass emission since it hasn't for about 3 years now. (not running for about 1 of those years.)
It seems to run great, but I can't seem to pass. it is way to high when idle and running with the test. I have swapped plugs wires cap and rotor, and i should say that it is clocked 10 degrees. Could this make it run high emissions? Have any of you run into this? What is the correct clocking on this motor? Should it be running at Zero? Could a coolant temp sensor cause this? idea's free things to try i'm down for this all. Let me know, thanks guys!!!!
