Spray-type carb cleaner into inection system Q

["stupadazzo2002" <mopar2me@xxxx>]

(This may be a re-post but I can't remember any replies)

Are there any consequenses of spraying carb cleaner inside the top of 
the fuel injection system (without air cleaner)with the engine 
running?

I noticed for the first time today I have black build-up (which has 
only recently started) inside the intake and on the diaphragm 
entering the system. I warmed the engine and sprayed a spray-style 
carb cleaner into the top while running the engine around 2000 RPM. 
It belches a horribly poisonous smelling cloud when you do this.

Will this spray-style carb cleaner harm the engine, exhaust, 
catalytic converter, or especially the O2 sensor? I just had a new O2 
sensor installed and I don't want to ruin it. Anyone? Is there a 
different recommendation? Or can I do this safely?
