If you just want to pass, get yourself a gallon of denatured alcahol.

in about a quarter or less tank of gas and your readings  will just
about vanish.  It's also non detectable since it burns so clean (just
water vapor and C02, nothing else, it merely dilutes the exhaust gas.) 
The best thing to do is fix the problem, because if it isn't running
right, you're not getting the best power or economy from the engine.
