1993 chevy 1500 Silverado suddenly no power &bad gas mileage. Sign In

I have a 1993 Chevy 1500 Silverado and the truck was running great and now all of a sudden it has no power when driving down the road and very bad gas mileage and when I unhook the EGR it runs better. I have replaced the fuel pump, fuel filter, EGR valve, spark plugs and wires, rotor and cap. Do you have any idea what my problem could be or any ideas of what I could try next. It literally went from running great one day to this terrible the next. Thank you for your help! Also, forgot to tell you the check engine light is not on.

I had bad power loss on my '93 1500 (not the bad gas mileage, though I probably didn't drive it enough running poorly to gauge the mileage).. but I ended up replacing the throttle body (got a used one), and that took care of it.
