You have a 2.4L, correct? If so, then you only have one bank. So if it is almost stalling when spraying an injector then it could be not sealing but that would normally cause a fuel leak. So I attached a diagram of the things around the injector. I am thinking there is something like a PCV hose or something like that around there that is pulling in the fuel. Basically something is pulling the fuel in causing it to run too rich which is causing the engine to bog down.
