WHICH WAY WOULD I TURN MY DISTRIBUTOR TO MAKE IT RUN LEANER? HAS ANYONE EVER TRIED THIS TO PASS THERE E-TEST? OR ANY SUGGESTIONS ON WHAT ELSE I CAN DO. I DID ALL THE BASICS, PLUGS/CAP/ROTER/OIL CHANGE/K&N DROP IN FILTER LOOKED CLEAN SO I DIDN'T CLEAN IT, DID IT IN THE SUMMER. ONLY THING I HAVE YET TO REPLACE IS THE O2 SENSOR, I HAVE A USED ONE ON THERE.

TEST RESULTS AT 40KM

HC --- LIMIT 72 - RESULT 38
CO --- 0.4 0.7
NO --- 550 145

ANY INPUT WOULD BE GREAT.

well, when you turn your distributor you are advancing/retarding your ignition timing. It has nothing to do with fuel. BUT advancing your ignition timing will cause the air to fuel ratio to increase, thus leaning out.
A leaner AFR will raise combustion chamber temperatures and as a result may cause your other readings to increase. Not to mention increase the risk of detonation occuring.
Now, its not like they beat on your car during an emmisions test, but you should give your car a nice little rip (i would say at least highway speeds for 20 minutes) before getting the test done. And doing so with too far advanced ignition timing could potetially be very bad.
If and when you decide to turn the distributor make sure you are using a timing light, so you don't advance the timing too much.
You advance the ignition timing by turning the distributor towards the firewall and retard the timing by turning it towards the rad.

haha man just get a tuneup... the savings in gas down the long run will eventually pay for all the parts you just bought Then get some seafoam and run it through the intake manifold\gas tank\oil. Do a search for Seafoam, it does wonders.
