I switched to ls6 intake manifold and everything was fine. I decided to go back to stock LS1 manifold and when i did the swap i plugged the EGR hole on top of the manifold. I hooked everything back up and when i started the car it was revving to around 2.3 RPM's then idling at around 1.8 1.9 RPM's. I figured the gaskets were bad so i just put on some new manifold gaskets and checked all the vac hoses and everything was fine. STILL idling at 1.8 1.9 RPM's?!?! im stuck and have no idea what else it could be. I let it idle for a couple mins and drove it and was braking instead of hitting the gas pedal...

any suggestions???
