could be the pump or could be a valve problem. Start with the pump. Keep in mind this won't be a cheap exercise...

Yes TPS, the only thing it controls is the EGR valve, when it gets out of adjustment it lets the EGR open too early, all of our 100 series as well as 79/79's have that problem, easy to adjust, you can test if it is the problem by disconnecting the vacuum hose that opens the valve then take it for a drive, you will find the solenoid with the hose running from the round chamber located along the intake pipe over the tappet cover just unplug it and try
