EGR I've read to much...

I have an 03 with 40K, it's not my daily driver obviously. I had my first problem about a week ago got the EGR code. I erased it and it has come back a couple times now? My question is all I do is tow our toy hauler 10K no grocery store runs.

I have read every free minute I get for the last 3 days, now I'm in overload I'm taking a about a 4K trip in 2 months with the trailer and I want to have the problem fixed right.

I don't have the coin for studs and complete EGR delete at this point (expensive trip) but I've read about unplugging the EGR and capping off the plate, what is your input for the 03. I read about a plate that was for 03 04 is it as simple as that.

I don't have any serious mods straight piped 4" and AFE intake no chips or programers, I am on top of my services oil, fuel and coolant.

Thanks for any input

It will throw a code but it will not hurt anything . Just do it when the engine is cold, as the valve will be closed. The only issue would be blow by if you were really on it hard, but still no issue really.

edit: forgot to mention that no matter what you do, up to and including a complete delete, it will throw a CEL. The only thing that will get rid of it is a capable tuner like ans SCT.

Oh yeah, and make sure the truck is off (not running) when you unplug the EGR Valve. I just remembered that when I saw your post Chris, thanks.

I have read on some threads that the '03 and '04 trucks don't throw a code, but I don't know this to be true, just what I have read.

i have it installed, got the heads back from the machine shop today so the motor'll be going back together tomorrow.

my initial impression is the cost is good and the quality is top notch.

should have the truck fired up by friday, so i'll keep ya'll up dated. I'd imagine it'll be a good product, i've heard good things about it

Ok, with the engine cold all I do is unplug the EGR, does that keep the gasses from going through the cooler? If so is just leaving if unplugged a ling term solution?

If yours is an 03-04. It shouldn't throw a code for the egr being unplugged, only the 05 and up will throw an egr code, I may be wrong but I had mine unplugged before I got my tunes( the tunes shut it off) and I didn't get a code.

So with the EGR closed it bypasses the cooler? If so what is the point of the delete kit? I must be missing something, I suppose the exhaust could back flow through the cooler.

I was going to clean the EGR this weekend should I even worry about if I unplug it?
