I have a 2001 v6 mustang with a cold air intake that has a breathing opening that might have took in water and engine cleaner. I turned on my car after using engine cleaner and a power washed hose without covering the opening in the intake and I turned it on and my car started shaking and did not run good at all. I would step in the gas pedal and it wouldn't give me any horsepower and it would hesitate to accelerate and then it would knock. I don't know what to do to fix it. I did a full oil change, drained the oil over a day and out new spark plugs and the wires. Do I just let it keep running and change the oil again in 2 weeks so it can go back to normal slowly? Or do I have to rebuild the engine?

Not sure what a "breath opening is" . You probably just have water in the cold air kit or intake. I'd remove the filter and let it dry out, check all of the tubes to make sure they are dry. Make sure you didn't knock any vacuum lines loose.

distinct possibility you drowned an ignition coil as well.

If your car runs, I'd just let it idle and get it up to operating temperature for awhile. Sounds like you got water/moisture in a electrical connection or coils and it's acting like a short. The heat from the motor will dry it out faster than just letting it evaporate on its own. This may take some time, or if it's driveable, drive it. Keep an eye on the temps when idling though, just in case. You'll find it'll start to run better and better as it dries out.

Your motor should still be fine, and don't use the pressure washer in the engine bay again lol, lesson learned......

P.S. if you have access to an air compressor, blow out all excess water from the motor, there may be little pockets holding water yet.
