I have an extra set of brown tops and well i put them in cuz the injectors i have in now leak pressure off into the engine when i shut it off or in general the pressure bleeds off so i put these in and well they r clogged so bad it would not even let fuel through them. Ive searched the internet and could not find anything just how to clean them while they still kinda work by running the engine.. So Help?

There is a product that you hook up to the port on the fuel rail and run it through that way, but If they are not letting anything through at all you will probably want to take them off to clean them. Pep Boys sells an aerosol can of fuel injector cleaner. I don't remember what the brand is. I cleaned mine with a 6-Volt flashlight battery, brake cleaner (though I'm sure it's probably too harsh for this application), and a hose. They work great now.

If they are as clogged/dirty as you say, I would have them professional cleaned. Why? Because you will want them flow tested so they closely match. If you just clean them, if they're that bad, they certainly could flow considerably different between each other and that will lead to idle and other issues as the EECs in these cars cannot individually adjust each injector's fuel flow.

I agree 100% with JT..... get them cleaned / flowed professionally. Significant flow differences will lead to bad things (blown HG in a lean cyl comes to mind).

I have had several sets cleaned / flowed by cruzinperformance over the years. Local NAPA may also offer a cleaning service with somewhat shorter turn around time.
