ok, did a fuller service on the 91 (151k) and finally, I hope, fixed the bad temp sensor.
-it had original leads, and looked like original distributor cap and rotor. New ones have made a slight difference if any. Can't see much wrong with the old ones to be honest. They are spares now.
-a new fuel pump regulator makes a huge difference. Whole sound of the engine changed and it seems to have noticably more acceleration so obviously a few of the gerbil wheels were obviously in need of either more or less gasoline. I would not have believed it.
-the old pcv valve was probably original judging by how nasty it was and allowing air in both directions. Not sure what damage that could cause. The hoses seemed clear of oil but looks like some congealed gritty oil under the valve cover. Do I need to pull and clean it?
-a new modulator and all new vacuum hoses seems to have revived the EGR system. Not sure why I bothered but I guess it can't hurt. Probably just because it is so much easier than on the 93
-had to pull the thermostat housing to get at a bad ECT sensor. Looks like there was a slow leak of coolant from the rad hose at one time that has shorted out these sensors. The dash sensor still only works about 60% of time.
-No spare t-stat housing gasket so I had to make one with coolant system gasket paper from the local jobber. Do these last or are they temporary?
-could not break free the high tension fuel line bolts on the fuel filter to change it out. Does anyone know how to do this? I can't fit a breaker bar on an angle where I can move it get purchase and even a half inch ratchet would not budge it.

bolts,right. So i put the FRAM back on the shelf and said later. So later came quicker than I thought and I have a OEM one on the way. Figured so much trouble put on the quality parts.
