Guess The OBD Code!!
It's an 89 with a 460 5 spd.
It's got a brand new EGR position sensor. Now the valve itself is rusted and I can see corrosion inside. I can't get to it since my tools are in storage...I'm moving this weekend and have a ton of house stuff I'll be doing all week so I cant get to the truck to work on it.
I'll look into testing the EGR and reading the links you guys posted. I've cleaned all the grounds and went through the wiring harness fixing anything that was bare or loose. And still have have the stumble.
I've notice some stumble in the idle but it revs good and while driving the stumble starts around 2250rpm through 3000. Sounds like it missing.
Thanks guys for all your help. I'll be back on in about a week.
