Check distributor for play on the shaft
Also, Check your EGR valve for carbon. Clean and re-install with new gasket. What is your fuel pressure? Use a fuel pressure gauge and test for readings. Turn the ignition key to "run" (engine off). The pressure should rise to about 60 psi to 65 psi. Turn ignition off and watch to see how fast your pressure drops. After 3 mins. Your pressure should be above 55psi. Post back your findings.
