Car has been running a little rough (like it is needing to be cleaned out when they are to rich/fouling) after first start up of the day. Well pulled the plugs and pass. bank was black and drivers side nice and tan. I drive the car for 2-3 minutes and it seems to clear up. No spark plug miss/pop. When I take off or get on it you can definately see black in the air behind me. Compression checks ok, I'm running 10 psi and long tube headers. So for some reason pass bank is running rich. Changed plugs and problem still there. Checked for vacuum leaks but none found. Calling tuner to have tune checked. Anybody got a similiar experience?
