Soo I cleaned my engine bay today on my stang and everything went great, my engine came out spotless and everything and my car ran great when i was done. I did my friends engine bay jsut before and now his car is running horrible and idles rough. We pull out all his coils to make sure nothing got in them and they were dry. When we took off his intake, a sensor had a little water in it so we dried it out but it still runs weird..Coud it just be the sensor or something else?
