Last update hopefully with some success!
after I put in the new EGR and was still getting the code I decided to do a complete tune up. Delco plugs, wires, MSD cap & rotor (better heavy brass terminals), fuel & air filters, and an oil change. I also put a bottle of cleaner through the gas tank.
I just drove from Chicago to Ann Arbor MI (500+ miles) this weekend. I got the light again at first on my way to MI. While there and on the way back 300+ miles I did not get a code. Must have worked it self out. Keeping my fingers crossed. I think my MPG went up also.
As far as the o2 sensor goes, from what I have found on the OBD1 cars they only have one, and its before the CAT and is more for sensing temperature?
