Well a CPS wouldn't hurt anything to replace after 170K. and they are now cheap.

As for the fuel pump you should check fuel pressure. it should be 40-70 for spec but normally these run 55-70 or so. Also when was the last time the fuel filter was changed? Fuel pressure regulator screen cleaned?
Check fuel pressure. Then for $40 I would buy 2 CPS. install one and put the other in the glovebox. then see where you stand.

He means unplug. before you start it up unplug. it will force the PCM to read default values. if it runs better you need a new ICP sensor. To check fuel pressure there is shrader (tire valve) on the fuel bowl. here is a pic that shows the shrader and the ICP sensor
