Run rich much?hoser813 said:I failed the carbon monoxide and Hydrocarbons but passed the NO test barely. Im not sure how bad this is but failed the hydrocarbons with a 3.4 and the allowed is .8, and failed the carbon monoxide with 75 and the allow is 15. I passed the NO test with a 1.9 and allowed is 2.
yes, doing so will cause the car to run rich, and and will hurt emissions performancehoser813 said:whats the AFM mod? you mean where you open it up and move the spring back on that gear thing?
Bugwugger said:The easiest way to pass ANY emissions is to open the exhaust up right at the convertor. Make sure there is at least a 1 1/2in gap or more. This will let most of the gases exit before it hits the EPA sensor at your tail pipe. At least this has worked for me all 3 times on all 3 supra's here in Ohio.
So just make an giant exhaust leak? Before or after the cat? Ill go try that....Bugwugger said:The easiest way to pass ANY emissions is to open the exhaust up right at the convertor.

There arnt very many techs like that working at emissions stations. I did, however, have him do the safety inspection, and that was good because my windows are too dark.Originally posted by SupraDreamer44
my advice is to find a dirty mechanic and have him pass it for you. thats how mine was done we hooked the sensors to my engine then the EPA to the tail pipe of a grand am, I came out with great numbers!
And you're a douche bag. I was just asking if the tricks people have suggested actually work.Larry_A said:Your car is a POS & you are a moron. Good combo.
