can anyone identify where my car went wrong on this test?

Do an oil change recently? Did you warm up the cat before you took it in? Recent tune up? (plugs/wires/cap/rotor)

 

High Hydrocarbons in the emissions...wouldn't that indicate an oil burning problem, and/or bad catcon?

 

The HC shows that his vehicle is reluctant to burn the expected amount of hydrocarbons before they exit the tailpipe. A new cat will most likely fix that problem. Most people will do a full tune up before they go that route though. Not like it would be a bad thing anyways, but it is a process of elimination. Here is my checklist.

1. Have you ever used or race fuel, octane booster, fuel injector cleaner etc? This stuff can coat your cat and make it lazy to burn all HC's. A good tune up still may not help get your car where it needs to be, so replacing the cat will be a must.

2. If you have not used additives or race fuel:
3. Replace the cap and rotor.
4. Replace the spark plugs.
5. Check the wires for crappiness and replace if needed.
6. Replace the fuel filter.
7. Adjust the valves and timing if needed.
8. Change the oil.
9. Clean your air filter.
10. Heat up the cat real good.
11. Take your car to the station and cross your fingers.

 

well i ddi recently add fuel injector cleaner, the only thing that i hav not changed was the fuel filter, spark plugs and wires, other that the motor should be somewhat good. I am planning on changing the cat, or get a new OEM cat, what would the oem cat run me, or what would be better considering i plan on doing simple bolt ons, and i live in cali so smog is an issue.
Thanks for the replies.

If he had a bad cat, he would have failed everything...the cat is working.

 

so then what could have caused me to fail? any help would be appreciated even though i didnt warm the car up that long because the smog guy knew me and took the right in, do u think if i would have warmed it up i would have past because those results look close so what do you guys recommend,
Thanks,

Read the friggin link I gave you and what I posted.

 

Do you remember my run in about a yr. ago w/the BAR and shit? My cat was lazy and working, but I was not failing everything. I just wasn't passing the low end test. All in all we determined I should have never used race fuel and I was the jackass for that.

 

A new OEM cat will run close to 9 bills. I got mine for free cause my car has less than 80k and was failing somg when it should be passing.
