Everything's been changed-out except the wires,fuel pump,egrvalve and check valves. All new hoses, dist.cap,rotor,plugs,fuelfilters,oil,air cleaner,breather,pvc,each thing seems to feel better, but condition still exists. I get to work at 7am, but lunch or coming home, starts fine but a block away, stopped at a light, idles good, light's green, give it gas, and blaah..restarts get it in gear and I'm going but hesitates and if I let off the gas it dies again....or doesn't. Then runs great for two days.?!..I need to lose this stress. Could egr cause this, because smog tech says I need another one to pass smog but he says egr won't effect engine performance. True? What about octane?

EGR will cause this problem, but you can just unplug the vaccum line going to it and then put a screw in the vaccum line. Sounds like you may have a problem with your pickup coil, but usually they need to cool down when they get hot. Carb, TBI, or Multiport?? I would imagine it would have a carb. I need more info, but sounds like a choke problem or carb problem. Also check vaccum lines. Might be having problems with vaccum advance as well. Wish I could be of more help. Good luck.
