EGR Cruise Test failure

[jingusflob]

for sure what ECU.???????
we start there for sure on any Code 51 or Code 53
do not spend money yet.
ok?

Thanks for getting back to me so fast. My ECM is a 33920-70EC0. I do not have a smog requirement where I live. I just want the silly CEL to stop coming on all the time. I just finished reading another post about headers that you had previously answered. I have one of those Thorley headers with the EGR grove cut into the flange. I am wondering if that is part of my problem. But considering the CEL only comes on when I first start driving it for the day then I can get it to go out by cruising slowly, I'm not so sure. I am leaning towards the EGRT more and more. It does pass the bark test. And I see the EGR main move in and out when I rev the engine during the live test. So I know its working. I'm stumped. But i the 10K resistor will stop the CEL then I may end up doing that trick. I was just hoping I could figure out what is causing problem because I hate not knowing.

Thanks
