I installed this snorkel setup today http://www.geocities.com/pathfinderoffroad/snorkelmod.html
After the installation my nissan is running very rich, i.e. fuel smell from exhaust. It also revs a bit different than it used to. I think it feels quicker up to 4500 RPM but after that it lags going up to 5500-6000. Any ideas on how I can correct this, or does anyone think anything is wrong? I may just be freaking out about nothing. I know that there is an interesting air chamber that is removed to install the snorkel what exactly does this box do? (there is a pic of it if you follow the above link)
Thanks,
Joe
