Failed nevada smog help!!
Hola. Gots 1.8L v6 92 mx 3 with 201551 miles on it im in vegas so if any mx3 ppls in area wanna rock the airport tunnel let me know. But back to my question. Smogged my car here in nevada yesterday and it failed. 220 ppm is the limit here i gots 334ppm so the guysaid i barely failed. I didnt fail the idle like most i failed the hi speed rev test. Sumone mentiond since its a fail by such a small amount. It could be my computer. Does that sound right. I know i need a new front valve cover gasket. My 2nd spark plug hole has some oil in it from the bad gasket. Could that be it. Also where can i get a valve cover gasket. Meyerz is the only one that carry it here butthey want 80$. Ive never heard of that much for a stick valve cover gasket. Bak to my question. Any one know any sensors i could check tips tricks anything.

I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant.

Re: Failed nevada smog help!!
First thing would be to fix the valve cover gasket, you can find a set on ebay for real cheap. And just do your basic tune up which consists of air filter, plugs, wires, distributor cap and rotor button. And it might not hurt to change the oil while your at it. Are you throwing any codes?
Re: Failed nevada smog help!!
I jus did an oil change few days ago. It has new plugs cap androtor ppm of hydro carbons

Could be a number of things with 200k on your engine.
Leaky injectors
Bad O2 sensors
Clogged CAT
Bad Coolant Temp sensor
ECU
Basically anything that has to do with emissions and fuel delivery.
Questions:
Have you run a diagnostic on your ecu? (it doesn't have to be showing a CEL)
Have you done any of this work since you've owned the car? A
What kind of mods do you have?

Re: Failed nevada smog help!!
Whats a CEL and can i use an obd2 from autozone. If so where is the port for it
Re: Failed nevada smog help!!
CEL = Check Engine Light, and I dont think you can have it scanned at autozone. But im not sure because I have never had anything that is odb2.

Re: Failed nevada smog help!!
you don't have an OBD II car you have an OBD I car, Autozone doesn't test OBD I Cars anymore, you'll either have to read the faqs on how to pull CEL codes or buy an OBD I reader
