Emmisions Problem

[SilentShado]

I have a 1999 hyundai elantra. The car only has 105,000 miles on it and runs great. The only problem with this car with the exception of some rust, is the damn check engine light. Obviously as most of you know there is no passing the emmisions with a check engine light. I know the culprit of the check engine light but I do not want to spend the money as it does not affect driveability. One problem is the downstream 02 sensor and the other is the purge control valve, I'm wondering if there is a way I can trick the computer using resistors or such. I'm also willing to trade for a vehicle of equal value with no check engine light issues. Which blows cause I do actually like this car.

why not just buy the valve and sensor and put them on? they cant be that expensive

Purge valve my guess would be about 30, O2, same if you get a universal unless its HO2. Hell, purge you may be able to pull apart, clean it out and reattach and scoot past the EPA with it real quick.

your lucky, its a 99, you can pass with two notready codes....how fast does the cel come on after clearing the codes and taking it for a couple drive cycles?

you may be able to clear it, take it for a couple shorter drive cycles and pull right into the test center....did it on our 97 van and had the cel come on 20minutes after leaving the test station lol
