hey guys im having a problem. my car has spark, has comprssion and fuel. my spark plugs are black and blue smoke comming out of the exhaust. I am running rich. What i believe is happening is that there is too much gas flooding the combustion chamber and flooding the spark plugs. sometimes it wont run on all cylinders. When i unplugs the fuel pump and clean the spark plugs it runs well. Then eventually dies out because the fuel pump is disconnected. what is causing my car to run so rich that it floods the sparkplug. when the fuel pump is connected and the car does runi need to keep high rpms to keep it running.
What is the problems
Questions i have?
is it my pressure regulator?
Is it faulty injectors? how do you know if its injectors?
o2sensor? how do you know when o2 censor is gone?
maf?
any ideas? thanks jeff
