EGR stands for exhaust gas recirculation. So if it uses exhaust gas, its supposed to get hot. It would be weird if it didn't.

What method did you use to check for vacuum leaks?

Re: 95 chevy 454 Sign In
we disconnected egr it ran worse engine light comes on vagely for about 2 to five miles and goes off it runs great when light is on it runs like Sh!t when light is off it goes back to surging no power rpms fall rapidly at times when not aelerating and it feels like its not getting any gas. until i let off gas pedal. for me to keep up speed i have to pump the gas pedal for it to keep going.
