Alright I dont know what this could possible be, just recently my zx2 with 110,000 miles has started to run really rough at idle, and then when I get to about 1500 rpm, it runs just fine. I took it to a local auto shop to have it hooked up and it turns out that my second cylinder is missing when I idle. I dont know what it could possible be. I already changed my plugs, wires, and coil. Any other ideas what could be causing this? Any help or advise is greatly appreciated.
