so i have a little probllem i pressure washed my motor today and the wierdest thing happened like ill drive and push the clutch in and the idle should drop back down but will stay at around 3000rpms but when i stop rolling like stop driving it will idle at 3000 when clutch engaged then drop to normal idle idk what the problem could be if idk i got water in a sensor on the intake manifold idk what the problem could be can someone please help me if u have any ideas
i have a jdm h22a it was fine before pressure wash and the wierd thing also it doesnt back fire anymore when i let off the gas idk if that has anything to do with it
