My Ram 500 exhibits a slight popping at idle. Other than that it runs great, run-up and performance are fine. I am guessing that one of the injectors might be plugged or partially blocked.

1) Could that cause the popping?

2) Has anyone tried using automotive injector cleaner in their fuel?
If it works that would be a lot easier than taking the engine apart or sending it in for service. Since it runs fine I'm reluctant to mess with it.
