I swapped a JDM B16A into my EK9. When the car is first started it idles a little rough but starts right up. Unless I let the car warm up for a while it miss fires and basically runs like ****. It also did this when it rained really hard the other night. I have checked the IAT sensor and the ECT sensor for ohm resistance and the plug for voltage output. I have replaced the plugs, plug wires, distrubutor cap and rotor. Any ideas please help.
