Random/multiple cylinder misfire probable causes?

2000 Chevy Blazer 4wd 4.3L v6

My check engine light is on and i had a guy at work pull the codes and there were

egr stuck open

multiple/random cylinder misfire

and exhaust recirculation gases.

im hear that the erg can cause multiple misfire, but also a fuel pump, my gas gauge also wont go below half tank. any thoughts?|||Look for a vacuum leak. Look on the back of the flex tube that goes to the throttle body and make sure that the big vacuum hose is plugged in to it. It comes off real easy when you change your air filter and if you arent looking for it, you wont know its there.
