I have a Suzuki Esteem 1998 that wont start. First, I needed to clean my EGR valve so I did so using carb cleaner. Also I used carb cleaner to clean the intake manifold openings where the EGR valve was connected. Now, the carbon deposits from there have been flushed into the compartment where my spark plugs are. I believe this because every time I change or clean my spark plugs and try to start the car, the car wont start and the spark plugs have black stuff all over them.
