most likely you got antifreeze on coil packs look straight under rad hose is that where your spark plug wirs come from if so take compressed air blow that area off

Also check the ECU. Its in a bad spot under the front bumper right where a hose can leak on it. If the ECU or connectors get wet all hell breaks loose, exactly as you described.
