Emissions....

then your last bet is a new cat.. how much did you pay for smog, oct gas and those guaranteed to pass bottle since you fail 5 times.

running 91 octane gas in a car not tuned to burn it completely will cause your emissions to increase.

I don't know, probably 30 or 40 clams.

how old is the o2 sensor?? they are cheaper than a cat, and if old may drop you the 6-10 points you are seeking

you need a cat. find a good metal core one - they're only like $100. it's not going to hurt performance, either.

Lol @ emissions.


That is all.

Based on those numbers and not knowing your CO and NOx figures, you probably have a minor post AFM intake leak or vacuum leak.

Could you post all your numbers so we could see the entire combustion picture on your motor?

Most properly tuned cars can pass the govt smog rollers without a cat.

Here are my test results
HC: 226 PPM
CO: 0.61%
CO2: 13.42%

[GDA]

^ those numbers indicate incomplete burn/false rich condition due to intake leak or vacuum leak... complete combustion should produce CO2 dilution percentage in the low to mid 14% and when really, really running well optimally near 15%.

That low of a CO2 would be more indicative of weak spark on one cylinder due to wires and or coil issues but its still tough to tell from the other side of a desk and not knowing the car.

Did they also share O2 and NOx?

To learn up on it yourself to troubleshoot, you should do a quick 15 minute read on this...

I'm not seeing any corroded or worn out tubes. I don't really know what I'm doing of course, but they all actually look brand new.

Could this possibly be cause by an advanced timing chain?

Also, I read that article. Very informative, thank you. I'm pretty sure I've had an intake gasket leak for awhile so hopefully that's the problem.

hey guyzzzz, I can't figure out why when i turn my shower on, i get wet. is there any way for me to stand in there without me getting wet??? I tried an umbrella, but a few drops keep getting on me. I also have a problem when i piss into the wind, it keeps blowing back and getting all over my pants-- I don't wanna turn around though, any ideas?

wtf??? really now!

My car is registered at my cabin :) no emissions there

[KirkerBezerker]

Not sure what AFM stands for hah

You have a lot of reading to do. Did they teach you how to use the search feature during the semester you spent at Nunya Community College?
