I believe that my fuel injectors might need to be replace. The symptoms include it idles too high. strong smell of gas when its running. and it stalls when i start it sometimes. the acceleration is bad also

 

May very well just be your fuel pressure regulator. They will produce a lot of fuel smells.

Remove the vacuum hose that attaches to the fuel pressure regulator, making sure the engine isn't running. If gas is in the line, your fuel pressure regulator is bad. Also, if there is none in the line, but, when you turn the switch on, fuel drips out of the hose, it is bad.

 

I agree with Zippy. FP regulators are probably the most common cause of fuel leaks/smells, especially on the 3.4L's.

 

I honestly never had a FPR fail on a 3100 or 3400. But my experience says a strong smell of gas can also be a sign of a leak. I would start with validating you have no leak. If you do, depending how bad, that could be causing all kinds of weird issues.
