Dumb Question

This is dumb I know but i have the 98 Intreque with the 3800 motor in it.I was wondering with my car running,when I disconnect the wire for my EGR valve what should happen?

I did that on mine and nothing happened.No lowering idle,puttering,skipping nothing.Is that what its supposed to do or?

From what I've read the EGR helps fuel economy and will keep your check engine light off as its wired with the emissons electrical system. Also if I clean it, it might boost fuel economy.

I also have a question when I had a check engine light for my O2's and Cam Pos Sen before I just changed the parts and the light went off automatically a few miles, minutes later. What would you call that, I've heard some names but don't recall it? But its a good part of the car as other cars will require a OBD2 scanner to delete the codes and reset the light. This car will do it for you and prove that the problem was sloved by running its own test.

My EGR valve does not set off a code or make the engine idle any different either. I had to replace mine when I bought my 2002 3.5L some mice had chewed through the wires and hoses.

This wasn't a dumb question. I am sure even the most advanced mechanics can still learn alot from these forums
