If you are soliciting help, would you be so kind as to provide a little more info.

Joking aside, you will have to provide a little more information for help. e.g. Has the car been tuned? Have you changed anything recently? Are you running MAF or SD? Do you have a log file or tune you can post?

Also, it is not uncommon for tighter LSA's with overlap to idle rich. Sometimes it is necessary to provide a little extra fuel to manage a more stable idle. I don't remember how much overlap there is on that cam off the top of my head.

1) How are you determining that your car is "running rich?" Are you having the symptoms of a rich vehicle? Or are you saying it smells bad? Or is your gas mileage suffering more than usual? Surging? Bucking? Poor throttle reponse? DTCs? Are you guessing or has this been verified in any way? I hope you're not going by your Autometer A/F gauge...

2) Replacing your NBO2s with WBO2s will not help one single thing. In the words of Samir Nagheenanajar from Office Space, "Yes, this is horrible, this idea..."

3) TAKE IT BACK TO YOUR TUNER OR FAVORITE SHOP, if you are not sure of how to diagnose the problem, or not really sure about the how's and what's, or if you are not sure that there's a problem at all, your local pros will be more than happy to help you

otherwise:

Please be clear and concise if you expect any real help or consideration in this forum

It's true


Maybe it's the oxygenated gas they use during the winter months and your gas mileage has just gone to crap just like everyone elses....
Or take it to your tuner and have them fix the problem.
