I've got a b18b1 in my eg hatch. Basic bolt ons aem cold air, custom 4 into one header,exhaust, msd ignition. I recently put on a skunk2 pro manifold and I'm having issues with the idle. I used the factory throttle body for the time being. All sensors are good. No vaccum leaks. I've tried adjusting idle at the the throttle body with little response. Its idling right at 3k. Anything I may have overlooked? thanks much in advance
