p.s. I put NGK Laser Platinum plugs in it ($40 that i find well worth it in combination with premium gasoline by the way)...that wouldnt cause it would it? I had them special ordered so i know they were gapped correctly.
Putting Premium gas in your civic will do absolutely nothing except break your wallet. There is no need for it whatsoever. Civics actually run better on what they are made to use, which is regular unleaded. It's built for the intentions of fuel economy, and people always seem to have this sense that premium gas will make it run better. It actually makes it run too rich if anything.
