You are using too much fuel, thus the black smoke .... try a short highway drive... if it doesn't clear, then its garage time to have the system reset. did you foul out the spark plugs? and how did you clean the fuel injectors? it is normal to expeirince smoke and it should clear soon. just drive for about two or three miles.

Yes you can. It takes some practice but you have to swallow the smoke like you would if you were trying to burp, wait about 15 seconds and then do what you would if you were going to pee.
