ok, pictures of my mess.

here is the mech. temp gauge in place of the "gauge sending unit". the mech probe is in blue, and the old "gauge sending unit" is in red.



now this is what i just came upon...what i think may be the gauge sending unit in red.

Yes, you removed the wrong one. Looks like you realized that by the second picture. :rofl:

I think the stalling is ignition-related. Usually, but not always, EGR troubles will cause surging, hesitation, rough running,etc. before stalling a vehicle. The EGR should be easier to troubleshoot, anyway. NM the neutral saftey switch code for now. You can also bump the timing.

The EGR code 33 is pretty simple to check using the Haynes manual, your checking to see if you have +5v and the checking the ohms across 2 pins. More than likely yours did the same thing as mine and the diaphragm inside the EGR valve got stuck. I was able to push on it with a screw driver from the holes on the bottom of the valve (you don't need to take it off).
