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.
