New to this site. Have a 1985 GS, 12A. Mods include RB headers, K&N filter, RB exhaust with Cat(don't know manufacturer). Runs great. Car has passed previous tests, but will not pass now. Told may need new carb or adjustment, local mechanic can't figure out. Looking for someone who can help pass the test.

My car is having trouble passing emissions, but I have new spark plugs, filters, cats, etc. What do I do?
J-rats Recipe for cheating emissions if its ABSOLUTELY necessary:

1. Turn variable resistor to full lean, or as lean as you can get and still run.
2. Trick ACV into pumping air to the cat all the time by removing the FORWARD UPPER vac hose, and capping it.
3. Run 87 octane
4. Run your tank down till your almost empty.
5. 2-3 bottles of alcohol in the tank. Drive VERY GINGERLY to the emissions station.
6. Once you pass go, DIRECTLY to a gas station and fill up with regular unleaded.

 

True, true...except this is the 1stgen corner.....here's a little more

Emissions search help, best one
