Ok Im currently trying to get my 96 civic w/ B18c swap BAR'ed. I have not taken it to the ref yet but I have been chipping away at this problem using the smog test mechine at work.

THE PROBLEM: Car won't pass smog at idle because of HC(numbers below). Its ever so close to passing but just not quite. I did have to mess with the throttle body at one point while installing my skunk2 manifold because I changed the throttle hat and had to adjust that little screw because the throttle was sticking. problem? Also I checked the O2 sensor and it doesnt cross count very fast at idle. could this be a problem?

Emission numbers - IDLE: HC 120-140, NOx 5, CO .03%, CO2 14.5% 2500 RPM HC 20-45, NOx 25, CO .05%, CO 15%

One last thing does anyone know if the ref always tests cars on the dyno even if they are registered in a regular smog area? If so I have not been testing it under those peramiters.

So yeah thats whats going on. The car is going to the ref with everything stock except the skunk2 manifold. Its got a stock GSR cat manifold and eveything USDM and p72 ecu. The swap is super clean and should pass visual in an instant but just the high HC at idle worries me.
