|  Failed Emissions Test, Please Help... Man I just failed my emissions test today. I had a feeling that it might happen, but I was hoping that I would be relieved, and I obviously wasn't. Here are the test results: 1. Gas Cap Check (Pass) 2. EVAP Components (Pass) 3. Hydrocarbons (Fail) My Car registered at:2.50 (g) State applicable: 1.60 (g) 4. Oxides of Nitrogen (Fail) My car registered at: 3.43 (g) State applicable: 2.50 (g) From reading the numbers, what should I have done to my car so that it will pass the 2nd test. I know for a fact that I need to have the spark plug wires connecting to the correct spark plugs. I had a feeling that they weren't in the correct sequential order, and when the guy at the emissions gave me the list of problems that I may be having, one of the reasons was the problem I just mentioned. Other problems could be the catalytic converter, etc... I'm sure you guys know more about this stuff than me, so I am asking advice as to what I should be looking to have repaired before my next test. All advice is appeciated. Thanks Last edited by thepremier : 06-29-2006 at 03:03 AM. Reason: typing error |

| You need to get results with a good tuned running motor. That includes plug wires on correct. Also to help you we need to know your setup, chip, inj, etc. Is this a Turbo Buick? no car listed either?

| If plug wires were switched, it would run really rough, and probably get much higher readings on unburned HC- if the car is a turbo Buick. The coilpack has numbers for the wires, so it's pretty easy to check.

 | get the engine running correctly then go back. that should fix your HC problem. as for NOx it could be as a result of that or it could be from a non-functioning EGR system. NOx is caused by high cylinder temperatures, and the EGR will help cool the cylinders down to reduce the amount of NOx
