I think the injector cleaner will make it run to rick <IMG SRC="smilies/eek.gif" border="0"> retard the timing a few *'s and put in fresh plugs and air filter.run out that gas or drain it and run some fresh clean stuff.
Rudy from Petroworks once gave me a tip that helped : I had a Samurai that on pre-test was a gross polluter. He told me to run a bottle of "Guaranteed To Pass" additive in my tank from Pep Boys, about $7, run the tank out, and refill with 9 gallons of 92 octane and a gallon of DE-NATURED Alcohol. Run it for about 50 miles and go to the test facility. I tried it and emissions went from 3.20 to 0.01. The test official couldnt believe it was the same motor. It worked again later on a Buick. I havent tried it yet on my Yota, but will in 2 weeks when I have to do mine.
Dude here checked my timing after the test was passed, then failed it due to timing being off a few degrees. Make sure the cat is good and all lines are hooked up where they belong. Fresh 92 octane gas and clean air filter, change oil as mentioned above.
We have to get checked in Washington but only certain areas, the city. The good part is, if the exhaust sniffs clean, they don't mess with anything else. I started adding goodies to the engine and taking the emission stuff off, I left the cat and PCV on but that's it. It's cleaner than it was before I started. Now that I know it passes, I have to get plates and plug the stuff that's disconnected but not taken off.
Thank God we do not have smogs here. In DFW, I had to pass a couple while I lived there. On one, the dude said I barely, barely, barely passed. Then I moved back home and Ido not have to worry about it now! <IMG SRC="smilies/smile.gif" border="0">
Ask the tech if you can take it down the road right before he smogs it. Floor it and get the cat nice and hot. Like stated earlier, retard your timing a few degrees. You are allowed to retard it some legally. Keeps the exhaust warm and can help a tired cat.
Usually if a vehicle is going to gross polute the smog machine will go through the visual inspection one more time. This is when you hope the tech aborts the test - gross poluting sucks!!
RockCrawler is right on. I was told a similar trick and it's worked for every vehichle I've ever had doubts about. Run your tank to almost empty and then put about 6 or so of those dry gas treatments into your tank. basically, you'll be burning mostly alcohol during the test. also higher octane gas will help. I also usually change my oil and plugs right before. just make sure you've warmed up the truck for at least 1/2 hour (sitting in the driveway doesn't count). good luck
Gadget is right. If you just get it nice and hot befor you test it then you should pass.
I know my dad took his old blazer to a local shop and it didn't pass. Well the dude told him to get out on the interstate and get it up to 75-80 mph for about 10min and then come back. He went back and passed the same day.
I do it every time!
