These are your stock injectors.

You didn't mention your current mileage or your issues with it.
Current mileage is 175K and there are no issues that leads me to believe its a problem. Im just trying to be proactive and tackle things as they come up and thought that this could be a service/mod situation.

He also flow-benches the injectors after the cleaning to insure they are balanced and sends a full report so you can see what they were before and that they are balanced now.

You may also be able to find a local guy that can do the same. This is a much better option than buying Chinese injectors off of FleaBay,
Im not sure if these parts come from ebay but I purchase mainly through ZZP
