turbotime

Hey my car is idling really high (1500 rpms). It is sorta cold out today and im thinking maybe becuase the fitv is bypassed it is running weird? I just have a plate blockin off the fitv but i think i might try fixing the fitv and reinstalling it (theres a post somewhere here that tell you how to). Could the fitv be causing my issues?

Also the car is really herky jerky sometimes in wet weather. What would cause this? Engine is built, and running hondata , tuned. I was thinkin maybe the partial throttle isnt tuned well but then again it only happens in WET weather (The herky jerky).

Any Ideas? I took out my plugs and they all look perfect except cylinder 4 appears to be running rich...? very strange need some insight
