Does a defective EGR valve affect the idling of a car?
My 98 Prelude timing belt tensioner broke loose while driving on interstate highway. My car was disabled so I had it towed and had the timing belt and all the parts replaced. Everything works fine except it dies at idle.So the idle was raised at twice the recommended idle speed at 1500 rpm. What do you think is the problem?

if you block off a working egr valve does it affect you performance ? my buddy says yes that you lose hp ,but i say no that you gain slight hp 1-5. cause all it does is allow co2 to go back into the engine.
did you ever think it may have jumped timing and bent a valve?

The EGR is only open at part throttle. It's purpose is to cool the combustion temps during the stoich conditions of closed loop operation. It is also beneficial for reducing NOx emmisions (during part throttle). It is closed during open loop. Blocking the EGR does not increase performance.
