Subject: So My Car Failed Emissions... by Randyj75 on 2009/5/15 0:42:51 My car (1990 L98) recently failed it's emission test for high NOx. The is basically stock w/ 24lb injectors, true dual exhaust w/ cats, and a custom chip to delete the EGR, which has been removed. The car has a recent tune up, w/ new plugs, wires, cap, fuel filter. It had it's intake removed and resealed using FelPro gaskets last April. Other then that, the car runs great, w/ no problems at all. Mileage is about 102K. The strange thing to me is that it was well within the limits of the other two categories. This what the test said; hydrocarbons 1.4000gpm -0.4612 pass carbon monoxide 30.0000gpm -5.1493 pass oxides of nitrogen 2.5000gpm -2.8883 fail Anyone have any ideas as to why it failed? BTW, I know that deleting the EGR is part of the problem. Thanks, Randy |
