Ok people a couple of months ago i put long tubes on my car...in order for the long tubes to fit i had to bend my egr tube...instead of doing that i just deleted the whole EGR system...Ever since then it runs funny...When the weather is nice and sunny it runs fine but when it rains it idles rough and runs like it has a miss...any input...i havent deleted the EGR in the computer yet but i dont think that would have anything to do with it considering it runs fine when its sunny...im thinking maybe MAF or bad o2s...oh and it runs great at wide open throttle no matter what weather...it just messes up when your taking it easy putting around town...

I think it wants it's EGR tube back. Possible to custom form one?

You NEED to retune your car for the egr delete. The egr only functions below 3/4 throttle on the 3.8L. that's why you're not feeling it at WOT. It's not hurting anything, it's just expecting more hot air to be recirculated through the manifold. You adjust the tune and it'll run as good as it did straight from the factory.
