Emission System Warning Light

Have a 2004 6.0 PSD. Cruising down the freeway, light came on. Any suggestions to keep me away from the dealer? Thanks!

Thanks Ruben. Did you have any issues with the way it ran with the bad injector? Can you have a faulty injector and still run as usual? Mine is unchanged from before the light went on.

Well,

The first time the light came on I was coming from Arizona hauling my Travel Trailer. The performance never changed a bit. It did well on the hills. I took it in and they replaced the EGR Valve, Light went away. Then a month or more later I went up north and thats when the light came on. we had 8 people and it was 4 hours each way. the truck rode fine, plenty of power and averaged 17MPG.

This weekend Ill probably head to Bakerfield and see how it goes.

Maybe I will try throwing on a new EGR valve and keep my fingers crossed. I am dealer phobic but if all else fails...

You guys using the fuel additive? Ruben mentioned the Diesel Kleen, are you happy with that? I am new to diesel powered vehicles.
Thanks again.

TOW4H2O,

Yup, I use Diesel Kleen. I dont see/feel much difference. I guess I just use it for peace of mind. Theres a thread going on right now on the 6.0 forum. It mentions some of the benefits.

Been using Deisel Treat, (made by Howe), since I got my Ex - added 1 mpg solid and it seems my filters are as clean as when they went in. Also, in 200K+ miles I've only had the water light come on once and that was after I missed a couple of additives. I use 1 oz per 10 gals.

My mechanic told me it will help keep the injectors clean too. He works primarily on the "Big Rigs" and has seen 350 - 400K injectors with seemingly little wear with regular usage of this stuff.

I usually get it at Pilot - 12 bucks a half gallon and it seems to last a long time. The only thing I have to put up with is the funny looks from the gassers at the fuel stop when I'm measuring it out in a shot glass. I just tell em that Everyone needs a shot!
