That is when the EGR opens.

I seriously do look forward to finding out what the cause of this is, not for the sake of who'* right and who'* wrong, I just realy would like to know as this one has truely stumped me.
That sounds like a reasonable test ...but then again, I don't have the car knowledge... can it hurt anything to run a car without it plugged in?

It will set a code, but it will not hurt anything. And it sounds like Bandit has the tools to easily clear a code so I did not think this would be a big deal as far as a test of the EGR system.

well for some reason my dads Tool doesn't want to clear any of my codes. so i really don't want any more in there for now.

If the TPS doesn't fix the problem, then ill move on to other things.. or just shoot the car

motorhead makes a good point, and this needs to be adressed
The EGR test is valid.
Eventually you will get to the bottom of it

Alright, let me poke my nose in here: :P

We have the values from the scanner that were posted, do we have a chart that shows what the values are supposed to be? Like maybe a chart in the factory service manual?

********* UPDATE ***********


Ok.. I did the EGR test.
Yup as far as one of my problems it fixed.
The problem where I hold the brake in Drive, Give it a little gas and chug / sputter.. That went away.

But my other problem at speed when it sifts in to OD and TR converter locks, That problem is still there with the Chug / sputter, But i think thats mt TPS, if you look at the second Chart.

And i confirmed that unplugging the EGR fixed the Low speed/idle problem by plugging it right back in and starting it up and it did the Chug again.

So looks like i might have two problems, EGR and TPS.

Bandit, I'm having the same 2 problems as you are. How did you test and fix the egr problem? Keep in mind that I don't have a scanner or what ever Meter you used.

there is a Plug that plugs in to the Top side of the EGR, Unplug it,Drive around, see if the problem goes away. If so.. You can try cleaning it. But that didn't work on mine.
So go to the Yard and get a New used one of Pay the $100+ for a new one.
Or i know someone will chime in on i forget his name that has rebuilt ones.

I haven't "fixed" my problem yet, i just know how to fix it

Didn't you say you fixed the problem when you take off from idle?
